Update to latest patch version of QGIS (3.28.6)

[MattF-NSIDC]

When opening the latest alpha of QGreenland 3 (currently unzipped at shared/QGreenland/QGreenland_v3.0.0alpha2), we're seeing this error in the currently-installed version of QGIS:

Looks like some work is needed to get a compatible environment.

I locked the environment myself, since the action seems to be failing to. I installed the same version of conda-lock as the action has, but I used conda instead of pip. I'm not noticing significant environment differences though, except that I have requests 2.29 and the action has 2.30.

I'm getting some error with locking the environment.yml file locally. Some error like this:

yaml.scanner.ScannerError: while scanning a simple key
  in "<unicode string>", line 60, column 1:
    <<<<<<< HEAD:environment.yml
    ^
could not find expected ':'
  in "<unicode string>", line 61, column 1:
    =======
    ^

Let me check what's happening, it could be that something broke too as you mentioned in #57.

That looks like a git conflict delimiter is in your environment.yml!

Ah oops, I reset the file and conda-lock works now (though I'm getting a different hash). Let me check on #57.

[MattF-NSIDC]

@weiji14 I'm working on a PR to fix that now! I think I figured out the cause.

The locking works again! Thanks @MattF-NSIDC for figuring out the dependency conflicts. Feel free to merge once the tests pass.
