Feature Request: Block Patterns for a 'Tip Jar' version of the donations block

### What

If we're able to make some tweaks to the Donations Block to make it less opinionated on titling - it would be great to have some Patterns which include it as something of a blogger 'Tip Jar'

### Why

The concept of a 'Tip Jar' is very common for bloggers. They often have a sidebar entry which asks for coffee money/tips - kind of single, one-off donations of small amounts for readers.

We've got the tooling for this in place with the Donations Block (with a couple of of tweaks) - but having some patterns to insert which include the donations block would make it a much lower barrier to including this kind of content.

### How

Start with concepting some Block Patterns which include the Donations Block and language/design elements around the 'Tip Jar' concept.

Start by reviewing the Donations Block and existing Block Patterns, then determine what titling changes are needed to make the block suitable for a Tip Jar. Done means the requested Tip Jar patterns and any required Donations Block adjustments have been defined and implemented.
