Added tests that check if Taiga.moe works as expected

[Statharas]

Hi Eren,

I have added two simple Specflow tests and the pipeline to run them via github actions that check if the website is online or not.

For maintenance, please take a look at the feature file included

Hi Stathis, thanks for the pull request.

I'm trying to understand how this works. Am I right to assume that the workflow runs after pushes and PRs by sending HTTP requests to taiga.moe?

If so, I'm afraid it wouldn't help, since the repository is not updated frequently. We'd have to be very lucky for these two occurences to coincide, and visiting GitHub to check the test results is not much better than simply visiting taiga.moe.

More importantly, the website has been offline only a few times in the past couple of years, and Taiga does not rely on it except for infrequent updates. I don't think automated tests of this kind is necessary.

Since the website has its own repository at erengy/taiga-moe, it'd be more appropriate to run related tests there instead of here. But once again, I don't think that'd be valuable.

Hi Eren,

You are correct, but it can be set up to run whenever, and can be set up to receive e-mails in case the website is not accessible.
