CLOUDP-298521: Decouple IPA Metrics Collection Job from FOAS Release GH Workflow (fixes)

[yelizhenden-mdb]

Proposed changes

Jira ticket: CLOUDP-298521

The issue arises from performing two checkouts in the workflow. When a second checkout is executed, it resets the current workspace, causing the previously checked-out files to be lost. To address this:

1. First, checkout the dev branch and upload the OAS file as an artifact.
2. Then, perform the second checkout to the main branch and download the artifact (OAS file) to continue working with it.

Still reviewing. Looking to see why we need to do 2 checkouts
