feat: Improve pnpm support for dashboard build scripts.

[FangSen9000]

I am working on the APISIX dashboard project to migrate its package manager from yarn to pnpm. His GitHub workflow uses this script to detect RPM packaging. We need some minor changes to make the workflow work normally.

Yes, but if the apisix build tool is not changed during the merge, the packaged RPM workflow of the merged PR will have an error. (after all, you are upstream of RPM workflow)

Do you want to copy this script to the local warehouse or request you to change this tool. We need to discuss it for some time. At that time, we will close this PR or request changes to the merge tool.

[FangSen9000]

WIP, however, I can be sure that all the changes to the tool are just these two lines

Update, the task has been completed
at apache/apisix-dashboard#2604 now

Wait for @bzp2010 's opinions

I think we need to wait for the PR merge in the APISIX Dashboard project before doing this.

BTW, I don't think using pnpm in the build session will help a lot with build speed, but it will improve our development experience.
