fix(lsp/health): ensure valid table before concatenating (#34930)

Browse Source 
The root_markers field can now contain a table of tables (as of
https://github.com/neovim/neovim/pull/33485) and :checkhealth will show
an error in that case since Lua cannot concatenate a table of tables.

Ensure that tables contain strings before concatenating and if not, fall
back to using vim.inspect().

(cherry picked from commit 5ad01184f3)
