Update stable dependency files

[github-actions[bot]]

Automatic update of stable requirement files to snapshot valid python environments.

Because bots are not able to trigger CI on their own, please do so by pushing an empty commit to this branch using the following command:

git commit --allow-empty -m 'trigger ci'

Alternatively, wait for this branch to be out-of-date with master, then just use the "Update branch" button!

Note that it is expected that the PennyLane-Lightning repo is a version ahead of the release, because the version number is taken from the dev branch. Trying to pip install from the files will fail until that major version of Lightning is released.

If pip install fails with a not found error when installing because of this, it can be fixed by manually downgrading the PennyLane-Lightning version number in the file by 1 version and trying again.
