[MPT-18998] Increased workflow timeout to 90 minutes (#228)

This pull request increases the build job timeout from 60 minutes to 90
minutes across several GitHub Actions workflow files. This change
ensures that longer-running builds have sufficient time to complete,
reducing the likelihood of jobs failing due to timeout.

**CI/CD workflow updates:**

* Increased the `timeout-minutes` value from 60 to 90 for the `build`
job in the following workflow files:
  - `.github/workflows/cron-main-e2e.yml`
  - `.github/workflows/pull-request.yml`
  - `.github/workflows/push-release-branch.yml`
  - `.github/workflows/release.yml`
