CI jobs @Github-Actions can't re-run individually

[Anirban166]

Not an issue with my package, but now that I look at the some of the pull requests or commits with a cross sign just because some remote workflow failed in one of the 11 checks I currently perform, I realize just how annoying it is to not be able to run that particular job that failed. Instead, we have to re-run all the jobs (checks on different platform) for anything automated by Github-Actions, such as the RCMD check am using across Windows/Ubuntu/MacOS, with 9 different releases covered. Travis conveniently allows to re-run a single job, the issue is isolated to Github Actions and now that I look it up, it has been already mentioned in the github community in this thread, where the OP expresses the same idea of the ability to re-run a single specific job.

It seems everyone is facing the same issue, with the common outcomes of build failure I experienced being either a MacOS specific issue: (runs fine locally, on Ubuntu/Windows, and via Travis)

or building the docker image: (that too mostly for MacOS)

Removed the workflow/job for the devel version of MacOS (release version is there) as it fails on initial setup randomly for some R binaries (not related to this repository's code) or other reasons such as failing to build the docker image.
