service/tika: init

[drupol]

Tika has been merged today (NixOS/nixpkgs#279059) so we need to wait 2~3 days until it become available here.

Once there, I'll set this PR in Ready for review.

I am also planning to work on a script that will initialise all the files required to add a new service, but for now could you also add a docs/tika.md file with a brief description for tika and a Getting started block with services.tika.enable = true;?

Further improvement on the docs can be done in a different PR upon coming up with use cases for using it with other services (I still have to update searxng docs as well, to use it with open-webui, I will do that soon)

Looks good! Only two things remaining:

1. Add a docs/tika.md file
2. Rewrite the commit messages to:

• feat(tika): init
• chore(searxng): use http_get

2 is because we use conventional commits to help during releases.

Done, should be good now.

Thanks!
