Add version checking

[xHyperElectric]

Context

Fixes #493

To check if the container is up to date on start, and if not link to documentation for how to update the container.

Choices

I created a VERSION file in /scripts and will use a GitHub action to update the version of that file. Then on container start (in start.sh) I query the GitHub API to check if the current version is equal to the tag of the latest version and if not I link to the docusaurus page for updating the container (this page hasn't been added yet)

Test instructions

I shelled into my container and ran the commands inside of it.

We need to add an action in workflows to automatically update the VERSION file. The docusaurus page (perhaps: https://palworld-server-docker.loef.dev/guides/updating-container) needs written

[xHyperElectric]

I am not sure how to go about changing the Github workflow file. I'm very new to Github actions. I know that something like:

- name: Update VERSION file
  run: echo "${{ steps.meta.outputs.version }}" > /scripts/VERSION

could update the version file but I don't know how the order of the actions needs to be organized. That action /\ would have to be after the action determining the semvar version, but I wasn't sure if you can modify files after checkout of the repo.

@xHyperElectric I'll have some time to work on this tomorrow, but in the meantime you can take some inspiration from this: https://stackoverflow.com/questions/74694675/adding-a-git-tag-and-version-info-to-docker-image-during-github-actions-build

@thijsvanloef I'm unsure on how to proceed with the github action workflow

@xHyperElectric That is ok, I will take a look at this PR later

Decided to go another way with the version checking #513
