don't disable cloud sync for skillmap

[riknoll]

this was regressed by #9546. I believe that change went out in arcade in march, so it's been broken for most of this year.

fixes cloud syncing of skillmap projects.

Now I question the popularity of skillmap

We should hotfix this right away.

it looks like that enableAuth(false) path was hit prior to that pr, that pr bumped it up a lil earlier but the original intention of the check was skipping for skillmap? https://github.com/microsoft/pxt/pull/7934/changes

or is there something else in between I'm missing there, like auth being enabled until workspace is set up then disabled after? either way change seems fine now just curious

[riknoll]

@jwunderl that linked pr is super old. if you look at the file prior to the change i linked, the check for enabling auth was looking to see if we are using the iframe workspace. the skillmap uses the browser workspace (see the ws=browser part of the url here)

the workspace was changed here #8290
