Increase Link UI search results when directly adding a Nav Link block variation

[getdave]

What problem does this address?

When adding a Navigation Link block variation (e.g. a Page block) via the Add block flow, the Link UI search results seem limited to only 3 results.

What is your proposed solution?

We should extend this to show the same number as when you click the + appender in the canvas.
