macOS Application fails to launch if .spyder_py3_dev does not exist

[mrclary]

It seems there is an issue with jupyter-client=6.1.13.

1. Delete .spyder_py3_dev
2. Start macOS Spyder application (built with jupyter-client=6.1.13)
3. Spyder fails to start

@dalthviz @ccordoba12, it seems the relevant change betweem #15149 and #15172 is jupyter-client=6.1.13 in the macOS app and @dalthviz discovered an issue with this version in 0984d4f. I propose changing the requirements for Spyder, even if provisionally, rather than patching install.sh.

[mrclary]

Looks like the requirement should be updated in spyder-kernels: 'jupyter-client>=5.3.4' -> 'jupyter-client>=5.3.4,<6.1.13'

[mrclary]

Also, as of this report, jupyter-client=6.1.13 is only available via pip, not conda main or conda-forge.

[ccordoba12]

I already talked to the Jupyter team and they're preparing a new release to fix that. Also, they plan to yank 6.1.13 in PyPI, so new PRs will use 6.1.12.

Let's wait until tomorrow to see what happens about that.

[ccordoba12]

The Jupyter team yanked both jupyter_client 6.1.13 and 6.2.0, so this shouldn't be a problem anymore.
