[Phase 3] HIP 28: Update submissionBaseDeposit

This HIP has been resubmitted to comply HIP-5 requirements of the title (needs to have “Signalling” and “Binding” on its title).

I recommend the proposers and authors to pay more attention when submitting these proposals, since there is a high risk that they could be challenged when submitting to the governor.

The framework proposal 5, pushed by Kleros, is the root of this beaurocracy, and basically each and every one of the issues to make policy quickly implemented.

I also suggest we update it to make it a less cumbersome norm.
