Record a major release for @clerk/mosaic.

@clerk/mosaic is a public package in the Changesets release workflow. This empty changeset releases no package, so the breaking rename from control to registerValue will not receive release metadata.

🐛 Suggested fix 
 ---
+'`@clerk/mosaic`': major
 ---
+Rename the useForm value-field registration API from control to registerValue.

empty changeset frontmatter in the release metadata to record a major release
for the public `@clerk/mosaic` package, and add a summary of the breaking rename
from control to registerValue.
