fix(diagnostic): clear stale cache on reset (#21454)

Browse Source 
The BufWipeout autocmd is not 100% reliable and may leave stale entries
in the cache. This is sort of a hack/workaround to ensure
`vim.diagnostic.reset` calls don't fail if there are stale cache entries
but instead clears them

Fixes errors like

    Error executing vim.schedule lua callback: /usr/share/nvim/runtime/lua/vim/diagnostic.lua:1458: Invalid buffer id: 22
    stack traceback:
            [C]: in function 'nvim_exec_autocmds'
            /usr/share/nvim/runtime/lua/vim/diagnostic.lua:1458: in function 'reset'
