ci: package and publish the Maya plugin to the GitHub release

Problem:
The actual plugin files for the Maya submitter:
1. Are not having their version number modified when we release a new version
   of the submitter; and
2. Are not made available to customers other than by requiring that they git clone
   the release branch of this repository.

Solution:
Modify the GitHub workflows to:
1. Overwrite the DeadlineCloudForMaya.mod file with the correct version during
   creation of the bump PR; and
2. Zip the contents of the maya_submitter_plugin directory into the dist_extras/
   directory during the actual release workflow. The shared release workflow has been
   modified in the .github repository to publish all files in dist_extras/ to the
   GitHub release page.

Effect:
With this change, we can have instructions for how to install the Maya submitter in
the package README that looks like:
1. Install the submitter support files into Maya using mayapy.
   Reference the Maya online documentation to find the location of mayapy on your system.
   e.g. For Maya 2024: https://help.autodesk.com/view/MAYAUL/2024/ENU/?guid=GUID-72A245EC-CDB4-46AB-BEE0-4BBBF9791627
   Follow the instructions in Maya's official online documentation to install the `deadline-cloud-for-maya` Python
   library and its dependencies to be available to Maya. For example, to install in Maya's default global location:
   ```
   mayapy -m pip install deadline-cloud-for-maya --upgrade
   ```
2. Download the appropriate version of the maya_submitter_plugin.zip file from the GitHub release for this package.
3. Unzip the maya_submitter_plugin into the location of your MAYA_MODULE_PATH.
   See the Maya online documentation on "File path variables".
   e.g. For Maya 2024 https://help.autodesk.com/view/MAYAUL/2024/ENU/?guid=GUID-228CCA33-4AFE-4380-8C3D-18D23F7EAC72
