VPA: Enforce Flag Documentation Update in CI

[omerap12]

Currently, our CI pipeline here checks for various aspects like linting and formatting.

With this PR, we are automatically generating flag documentation for all VPA components. To ensure consistency, we need to verify that whenever a new flag is introduced, the corresponding script is run. If not, the CI should fail the build until the developer commits the updated flag documentation.

To enforce this, we should add a new script called verify-vpa-flags.sh, which will:

1. Run vertical-pod-autoscaler/hack/generate-flags.sh.
2. Compare the output with vertical-pod-autoscaler/docs/flags.md.
3. Fail the CI if any differences are detected.
