Ensure default labels consistency across all packages

[delatrie]

Context

The following labels should be added to all test results automatically by all integrations:

• language: the value should be javascript.
• framework: the value should be the name of the test framework.
• package: the value should be a dot-separated path to the test file.
• host: the name of the host that runs the test. Overwritable via the ALLURE_HOST_NAME environment variable. It's used to visualize the tests on the timeline.
• thread: an identifier of a thread or a worker process that executes the test. Overwritable via the ALLURE_THREAD_NAME environment variable. It's used to visualize the tests on the timeline.

Default suite and BDD labels are subject to issue #1068.

The current implementation state

Package	language	framework	package	host	thread
allure-codeceptjs	✅	✅	🔲	🔲	🔲
allure-cucumberjs	✅	✅	🔲	✅	✅
allure-cypress	✅	✅	🔲	🔲	🔲
allure-jasmine	🔲	🔲	🔲	🔲	🔲
allure-jest	✅	✅	⚠️	✅	✅
allure-mocha	✅	✅	✅	✅	✅
allure-playwright	⚠️	✅	✅	✅	✅
allure-vitest	✅	✅	✅	✅	✅
newman-reporter-allure	✅	✅	🔲	⚠️	🔲

The legend:

• ✅ - the label is implemented; the implementation is consistent.
• ⚠️ - the label is implemented, but the implementation differs from other packages.
• 🔲 - the implementation is missing.

The inconsistencies:

1. ⚠️ allure-jest:
   • package': a value is deduced from the path to the test file's directory, not to the test file itself.
2. ⚠️ allure-playwright:
   • language: the casing of the value (JavaScript) doesn't match the corresponding values by other packages in this repo (javascript).
3. ⚠️ newman-reporter-allure:
   • host: a value is always localhost.

Helper functions to create some default labels:

import { getHostLabel, getThreadLabel } from "allure-js-commons/sdk/reporter";
import { getEnvironmentLabels } from "allure-js-commons/sdk/reporter";
