UI: Use native go:embed instead of go-bindata (thanos-io#6900)

* UI: Use native go:embed instead of go-bindata

With this commit we migrate from the no longer actively maintained
go-bindata project, to go:embed, for embedding the UI app into the go
binary.

Signed-off-by: Jacob Baungard Hansen <jacobbaungard@redhat.com>

* UI: Remove static react app from .dockerignore

Otherwise we cannot build in e2e tests for example.
