Add tests for Conferences script

[dragid10]

Fixes #384

TLDR Summary:

This PR does 3 things

1. Adds tests for the logic introduced in Ensure the conference URL always has a scheme #379
2. Refactors the Conferences script into testable functions
3. Adds wait time to the CI and tests so that playwright has time to get itself together 😄

What's new:

• Added 3 unit tests in tests/test.py:
  • When the URL in the issue is valid (has a scheme)
  • When the URL in the issue is valid (but missing a scheme)
  • When there is no URL in the issue at all
• Introduced startup wait time after serving the local site and before running tests: This was one I actually did hit a couple of times while testing locally. Playwright was very eager to just start testing things immediately when running tests, so I added a 5 second pause before running tests so that jekyll actually brings everything up as expected first

What's different:

• _conferences/__main__.py got refactored!
  • Moved most top-level logic into callable (and testable) functions
  • Added a "main" function to the script that orders the steps taken
• Introduced a delay between tests: playwright tests don't consistently work during CI runs. It seems like there is some internal setup/teardown that happens between tests that don't always complete in time for a test case to run. Adding a delay seems like an easy bandaid to slow things down enough to get them running more consistently

Those tests though:

I get all tests passing when I run the tests locally!

Other Notes:

I caught why the URL was always being changed to None as mentioned in #384, in the original logic I forgot to set the valid_url variable to a real value when there is a valid url found 😅
I was so focused on the unhappy path, that I neglected the happy one 😭

Edit: After a good night's rest, I think I figured out why the CI was failing. The GITHUB_TOKEN not being available was just a red herring. I've added commits to the PR to hopefully address the problem

Hmm interestingly enough, I'm able to run the tests just fine locally. I'm not at all sure why the CI doesn't think it's getting a GITHUB_TOKEN

@kjaymiller okay I promise I'm done making updates. This is forrealsies ready for review!

[kjaymiller]

How is the service started. I wonder if a fixture that starts the service and tears it down would be more reliable.

[kjaymiller]

Great work

really minor change and a question. looks good though and about 99% there
