This PR adds contour to endoflife.date project, let me know if it needs more improvements, I have tried to cover most details from upstream, thanks for maintaining it!

Other than suggested changes:

Adding two unsupported releases will be helpful to users (1.25 and 1.24), with the eol dates adjusted for them accordingly.

Q: As per my understanding, new features only happen in a .0 release, so no release cycle sees active development. So a x.y.1 patch release will never get new features. If that's the case, we don't need to add Active Support column, but I'd like to confirm this.

Rest looks good to me, thanks for your contribution

Thanks so much for the detailed review and your time @captn3m0!
I think I have resolved most of your suggestions and regarding your questions, I am new to this project so I am a bit confused about the Active Support column, are you referring to eolColumn: Bug and Security Fixes? If yes, I think the project mentions that its patch release deal with only that and that's why I kept it, let me know if you think we should remove it, I will change it

Thanks again for doing it!

I was asking about eoasColumn, which tracks Active Support (See https://endoflife.date/drupal for example) to track if new features are included in support. Reading the links, doesn't looks like that is the case, so we can ignore it.

I'll do a final review and merge soon, thanks for your contribution.
