As we are bumping the qhub-jupyterhub-version that depends over these changes, we need to be sure Quansight/qhub-jupyterhub-theme#13 was merged and a new release was made

@viniciusdc I'm waiting to review this PR until a release of qhub-jupyterhub-theme is released.

Thanks @viniciusdc, this looks great!

Could you fix the typo, and then feel free to merge :)

This linter is falling due to a broken link that was fixed in #1269 (this branch only does not have those changes, so that's why the action is complaining )

@viniciusdc I'm not sure why it's not appearing in the "check" above but going to the files changed, you will see what I mean. There are other misspellings in files you didn't touch but don't worry about those.

Let's move those fixes to another issue and fix those later (I think some were already managed by newer changes to the main that are not reflected here). For now, lets just disregard those typos 😝
