Updated release GH action workflow files.

[iamdharmesh]

Description of the Change

As discussed in #412, currently, the release zip archive not getting attached to the GH release. Earlier Generate release zip workflow was common between the release event and workflow dispatch event, but somehow workflow was not getting triggered on the release event. (Note: in b8d8d2c we updated the file to follow what we are doing in the distributor, but it creates zip without build files)

This PR updates release workflow files to fix the issue and also adds workflow dispatch generate zip workflow to manually generate a zip archive.

Closes #412

This can be tested after the PR merge.

• Verify that the "Generate release zip" action working fine.
• Verify that the stable branch is updated with build files when we push anything to the trunk branch.
• Verify that release zip archive to new release.
