Update RAMP4 version via github workflow

[dnlnashed]

For #86

Changes

This PR adds a github workflow that allows the user to enter a version they want to update RAMP4 to. Accepted versions are ones supported on the RAMP4 npm package. Once ran, the workflow will create a PR containing the updated RAMP4 version.

Notes

• If the workflow does not work, some repository settings may need to be updated. If you go to Settings -> Actions -> General, select "Allow all actions and reusable workflows" under Action permissions and select "Read and write permissions" and check "Allow Github Actions to create and approve pull requests" under workflow permissions if not already set
• In main.ts, the .css RAMP4 import ramp-pcar/dist/ramp.css is in a different location for RAMP4 versions 4.8.0 or lower (ramp-pcar/dist/lib/ramp.css). As a result this line needs to be updated when using those versions. The workflow should account for this and change this line accordingly depending on what version you use.
• Currently this PR updates RAMP4 to 4.10.0 using the npm package
