Fix non-standard NatSpec

[jaybuidl]

Change

Prefix the following RAB tags with custom:: authors, reviewers, auditors, bounties, deployments, tools.

Motivation

As @greenlucid found out, our current RAB annotations does not conform to NatSpec and some parsers choke on it.

This would apply only to new undeployed contracts.

Note: the @author tag singular is standard NatSpec but @authors is not.

Example

Example seen in the wild of custom co-author natspec

/**
 * @title ...
 * @custom:version 1.0
 * @notice ...
 * @custom:coauthor foobar (0xfoobar)
 * @custom:coauthor wwchung (manifoldxyz)
 * ...
 * @custom:coauthor ryley-o (artblocks)
