Add SemVer Label Processing (fix overwritten file)

[ericmcdaniel]

Another quick follow-up release based on v0.4.0, which overwrote one of the scripts in error. The CI/CD pipeline failed to populate the release title and notes using PR details. These issues are challenging to debug without just YOLO'ing it in the pipeline. :)

Calculates the SemVer in the CI/CD pipeline to use based on the previous releases' version number. Artifacts built during the pipeline deployment will have the calculated SemVer number embedded in firmware.bin.

Technical Details

Calculating what major, minor, and patch values to stamp is determined by what label was applied to the PR.

• If a contributor adds "major", the SemVer will increment major and sent minor/patch to 0.
• If the minor gets incremented, the patch set to 0. Major is unchanged.
• If no label is provided within the PR, then the patch value gets incremented. Major and minor are unimpacted.
