fix: regenerate protos using gogo 1.3.2 (#21880)

* Regenerate protos using gogo 1.3.2
* Add protos to generate, add checkgenerate to CI
* Address proto warning
* Add generator tooling to Makefile
* Delete recursive Makefiles, simplify generation run by goreleaser
* Use env bash for fetch-ui-assets
* Add static-data to clean target
