chore: update PR jobs to run build script and generate files

[SoniaSandler]

Main build job failed because of a permission error with the pnpm generate:subscription-v1 part of the build script. Now the generated files are not committed to this repo and the build script has been added to all pr jobs

[benoitf]

hello, AFAIk generated sources should not be committed (should be in src-gen, not in src)

[SoniaSandler]

@benoitf that was the first thing I did, but I think it was the linter that failed as the generated file was imported but didn't exist https://github.com/redhat-developer/podman-desktop-rhel-ext/actions/runs/14770043428
(Edit: I could add a pnpm build step in the PR check jobs to generate it)

[benoitf]

@SoniaSandler yes , as you said, it seems it would be nice if: either the linter command generates the file first or that the job calls the build command first

as long as generated files are not committed I would say, we're fine 👍 '

[SoniaSandler]

@benoitf okay, I'll remove the generated file from this repo and update the workflows

[benoitf]

thanks

[benoitf]

approving as it's an intermediate step to unblock gh jobs, removal can be a separate PR

[SoniaSandler]

@benoitf updated the PR workflows and removed the generated files. Merging as all the PR checks pass
