Removing schedules and adding guidance for RFHs

Why is this change being made?

Provide a detailed answer to the question on why this change is being proposed, in accordance with our value of Transparency.

Please add the details saying why, not just what in this section. Example: We have discussed the topic in Slack - (copy of Slack conversation). The current process is not efficient, this MR makes the description of X more clear, and helps move Y forward.

Schedule changes are too frequent to manage this through the handbook, also spreadsheet work better with slack integration bots.

Updating guidance on RFHs after collaboration with the Support Org.
