setlocal rtp, doesn't work in vim9 at least.

[McUsr]

Hello.
So, setlocal rtp doesn't work in vim9, if I am in a .vim file and I hit K on top of "map", I'm taken to the php-help for map.

When I check my rtp, by echo &rtp when the active buffer is a .vim file, the path to vim-php-manual is there.

I have fixed this by issuing an

  execute "rtp -=" . vimphpmanpath.

No big deal for me, when I had the fix, but I think you should update the docs, and make a fix.

Thanks for a great plugin by the way.
