Remove SIG Scheduling approvers from reviewers

[alculquicondor]

What type of PR is this?

/kind documentation

What this PR does / why we need it:

/sig scheduling

We currently have 4 approvers and 8 reviewers (including the 4 approvers)

I propose:

• To remove the approvers from the reviewers list (this PR)
• Any PR should be reviewed by a reviewer before being assigned to the approver. Reviewers are assigned automatically.
• If it's a hotfix, the PR can be assigned to an approver directly.

I hope this accomplishes the following:

• Lower review burden from approvers
• Encourage our reviewers to take more responsibility and build their reputation.
• Encourage new contributors to seek the reviewer status.
