Add PHP History Timeline

[mkurzeja]

Initial implementation of #1265

This adds two main changes:

1. New view of PHP History Timeline as a separate page. Events are loaded from a .json file

2. Adds link to the new page to the right side menu:
   

Events from years 2020-2025 are not included in this PR, I will create a separate one.

Looks great, thanks!

Please note Sara's comment (I suppose we can wait for others to weigh in as well).

IMO: I don't see a problem with web-php review for changes like this, as it's no more work than user conference review, but I'd be happy to hear from others.

Thanks, I get the point with the wiki idea, I just struggle a bit with some flows around it. Will summarize everything and reply to the comment directly.

Something strange happened with the visual regression test. Screen was updated, yet if failed again. I will check this again.

@saundefined we are now working on running the visual tests locally, so we can check why it fails.

@mkurzeja the last visual test looks awesome! 🎉
