Move XBlock Tutorial to XBlock repo

[sarina]

@feanil - depends on openedx/XBlock#686

[feanil]

The xblock docs will be available under this url: https://docs.openedx.org/projects/xblock/en/latest/ so I think we'll want the redirect to be somewhere under there.

[sarina]

They're at https://edx.readthedocs.io/projects/xblock/en/latest/xblock-tutorial/index.html so I assume this shoud be https://edx.readthedocs.io/projects/xblock/en/latest/xblock-tutorial/$source.html?

[feanil]

I've updated this so they're also published under the docs.openedx.org domain here: https://docs.openedx.org/projects/xblock/en/latest/xblock-tutorial/index.html

The docs.openedx.org domain version is the same content but at a more correct location.

Thanks @feanil added that in

[sarina]

@feanil do you know why the two checks aren't running (docs/readthedocs.org:edx-developer-guide and open-edx-release-notes)? We moved both of those guides anyway so shouldn't we remove these checks?

[feanil]

Looks like those two checks are required in GitHub but maybe no longer setup. I agree that they should just be removed from the set of required checks.

[sarina]

Hmm. I tried removing them from run_tests.sh but that didn't make the build icon go away (still says it's "expected"). I'm not sure how to disable the check otherwise.

[feanil]

Oh yea the update is in the github settings but it looks like this is actually related to a new change on the RTD side, I'm fixing that now.

[sarina]

Should I back this commit out? 140ab26

[feanil]

Yea, you should remove that commit, I think it's still good to test the redirect builds are working as expected and should be pretty fast.
