[📖 Docs]: Add Gitlab CI example

[thomascaillier]

Hello,

Since the code tested for component testing is served through local server (ViteJS in most cases), the pipeline is more tricky than other cases : we can't use a deployed Selenium Grid, if we want to use a Gitlab service there has to be a two-way network access between service and job... (i'm actually stuck in how i can do it)

So i thought it could be very useful to have a documentation and/or an example of how running component tests in Gitlab CI, what do you think ?

@thomascaillier the problem of component testing is independent from its location. Component tests are in a sense like unit tests and it doesn't matter where you run them, they should work fine locally or in CI. The same applies here. You should be able to run component tests with WebdriverIO in Gitlab since WebdriverIO uses Vite to load the assets wherever the test is executed.

If you have any concrete issues running component tests on Gitlab please provide more information.
