feat(lsp): update LSP healthcheck format (#28980)
This is mostly an aesthetic change, although there are a few new pieces
of information included. Originally I wanted to investigate including
server capabilities in the healthcheck, but until we have the ability to
fold/unfold text in health checks that would be too much information.
(cherry picked from commit 5d26934c7c)
