feat: build documentation when tagging

[tallpress]

Rather than relying on RTD's automation rules. We will trigger the build of the docs from the CI.
We are already doing this with dev docs and it works nicely.

Example HTTP req

❯ curl -X POST -H "Authorization: Token <TOKEN>" https://readthedocs.org/api/v3/projects/eva-python-sdk/versions/docs-v5.0.1/builds/

Does it set it as the default one as well?

Does it set it as the default one as well?

the default atm is always development, do we want the default to be the most recent tagged version?

[LouisBrunner]

Yes

[LouisBrunner]

As long as it doesn't conflict with RTD's automation rules
