Add docker files and instructions for debugging Selenium functional t…

…ests

This PR introduces new Docker files to enable debugging of Selenium
functional tests for Docker users. It configures a VNC viewer for
real-time browser interaction monitoring during test execution.

Additionally, a new section is added to the documentation detailing
the process of running and debugging Selenium functional tests
using Docker and a VNC viewer.

+# Debug Functional Tests
+This section explains how to run Selenium functional tests using Docker and debug the tests through browser interaction.
+
+1. Install a VNC viewer, such as [RealVNC](https://www.realvnc.com/en/connect/download/viewer/), if you haven't already. This will allow you to view and interact with the browser running the Selenium tests. The following steps are using RealVNC as a setup example.
+
+2. Make sure you have completed steps 1-5 in the [Docker Development Environment Setup](#docker-development-environment-setup). Now, ensure you have 5 files, `docker-compose.yml`, `docker-compose.selenium.yml`, `Dockerfile.selenium`, `entrypoint.sh` and `start-vnc.sh`. You can also download them by running the installer script. This time you need to pass a parameter `--ftr`.
+
+```bash
+curl -o- https://raw.githubusercontent.com/opensearch-project/OpenSearch-Dashboards/main/dev-tools/install-docker-dev.sh | bash -s -- --ftr
+```
+
+3. In the terminal, run the following commands to stop any running containers, build the new configuration, and start the containers with the Selenium setup:
+
+```bash
+docker-compose -f docker-compose.yml -f docker-compose.selenium.yml down
+docker-compose -f docker-compose.yml -f docker-compose.selenium.yml build
+docker-compose -f docker-compose.yml -f docker-compose.selenium.yml up -d
+```
+
+4. Under the Docker tab in VS Code, you should see three containers running: opensearchproject/opensearch:latest, abbyhu/opensearch-dashboards-dev:latest, and selenium-test.
+
+5. Right-click `selenium-test`, and select `Attach Visual Studio Code`. This step is the same as step 8 in the Docker Development Environment Setup.
+
+6. Connect to the VNC server running in the Docker container. First, launch the VNC viewer, then enter `localhost:5900` at the top and press return. You will see a popup window labeled `Unencrypted connection`; click continue. Enter the password (the default password is 123), which is configured in `start-vnc.sh`.
+
+7. After entering the VNC viewer, click the menu at the bottom left. Then click `Internet` to ensure Google works. Also, click `System Tools` and select `LXTerminal` to verify you can type in the terminal. The default terminal path should be `/docker-workspace/OpenSearch-Dashboards`.
+
+8. Run OpenSearch and OpenSearch Dashboards. First, start OpenSearch by executing `yarn opensearch snapshot` in one terminal. In a second terminal, run `yarn start --no-base-path` to start OpenSearch Dashboards on port 5601. Before running any functional tests, make sure OpenSearch Dashboards is running on port 5601. This process may take 2-10 mins, as it requires all the bundles to be assembled. Please be patient. However, this only occurs the first time you run it; afterward, everything is cached, significantly reducing the startup time for OpenSearch Dashboards. The initial bundling speed is dependent on your hardware limitations and VNC settings. Feel free to make adjustments to improve the process as needed.
+
+9. Open a separate terminal and update Chromedriver by executing `node scripts/upgrade_chromedriver.js`, followed by `yarn osd bootstrap`. This will update the Chromedriver version within the node_modules directory, allowing you to use a compatible version with your installed Google Chrome.
+
+10. To execute a single functional test, use the following example: `node scripts/functional_tests.js --config test/functional/config.js --include ciGroup9`. This command runs all the functional tests within ciGroup9.
+
+11. The Selenium tests will be executed in the browser, viewable through the VNC viewer. You can monitor the test progress in real-time.
