ci: add timeout-minutes to all jobs in functions.yaml (#3535)

Without explicit timeouts, GitHub Actions defaults to 6 hours per job.
Add job-level timeouts based on expected runtimes to prevent hung jobs
from consuming CI minutes unnecessarily:

- precheck:             15m
- test-unit:            30m
- test-templates:       60m
- test-integration:    120m
- test-e2e:            120m
- test-e2e-podman:     120m
- test-e2e-runtimes:    90m
- test-e2e-config-ci:  120m
- build:                30m
- publish-utils-image:  30m
- publish-image:        30m

Fixes #3530
