fix(mason-nvim-dap): correctly configure to auto-install debug adapters (#3493)

Tested with `php` and `kotlin` Extras. 

`kotlin` Extra doesn't have the debug adapter in Mason
`ensure_installed` and doesn't install automatically on its own.

`php` Extra has the debug adapter defined in Mason `ensure_installed`
and does correctly install automatically. However, this should not be
needed due to `mason-nvim-dap`. If you remove [these
lines](ed93ce9c15/lua/lazyvim/plugins/extras/lang/php.lua (L26-L33)),
then the debug adapter doesn't automatically install, but it should.

With the change introduced in this PR, both Extras automatically install
the debug adapters. `kotlin` Extra doesn't need anything else and in
`php` Extra the lines I mentioned previously can be removed or not. The
point is not to remove previously Mason dependencies with debug
adapters, but to correctly configure `mason-nvim-dap`, so in future
Extras you don't have to define the debug adapter inside a Mason
dependency.
