[Automatic Releases] "Major Release" workflow that is run manually

[AsherGlick]

Now that the weekly workflow is complete we can inherit, extend, or wrap it in another workflow that can be called manually using the workflow_dispatch configuration in the workflow file.

workflow_dispatch's configuration should takes in the description of the release as a parameter
The major workflow finds the last tag with the format. It is the same format that the weekly build will use to find tags.

/release-(?P<major>[0-9]+)\.(?P<minor>[0-9]+)\.(?P<revision>[0-9]+)/

Then puts a new tag on the current commit with the format release-{major+1}.0.0. Notably different from the weekly format as it is incrementing the major number instead.

Then it will cut a new release like the weekly workflow and use the description parameter from workflow_dispatch as the release's description.
