PR: Update conda-based installers

[mrclary]

Description of Changes

• Added StartupWMClass to Linux desktop file. This obviates the need to change the name of the desktop file in the post-install script.
• Minor CI workflow updates

@dalthviz @ccordoba12 I'm having trouble getting the Windows test to work properly; perhaps you guys have some insight.

The following should execute the exe installer from the bash command line in silent mode:

$ cmd.exe /C start /wait "<path to exe>" /S

I've successfully tested on my Windows VM (with bash shell), but can't get it working in CI. From the logs it appears that cmd.exe is executed but the executable path is not resolved properly: the cmd.exe banner is printed but the installer does not run.

I can see that you're not using a Bash shell to run the installer tests on Windows (i.e. there's no shell: bash in the Test Installer Application step). And I think the default shell used by Github Actions on Windows is cmd.

Hmm. For the build-installers job I am using a default shell defaults: run: shell: bash -l {0}, and the Test Application Bundle step is a bash script. And in the same step I've confirmed [[ -e "$PKG_FILE" ]] && echo "Installer exists" || echo "Installer does not exist" successfully reports that the $PKG_FILE exists while running in Windows.

Ok, sorry for the noise.

No worries, thanks for looking at it.

Looks good to me, thanks @mrclary!
