Move stuff into custom + Java + Copilot (#3)

* Move LspDetach handler near kickstart-lsp-highlight group (nvim-lua#900)

Moved to make sure the kickstart-lsp-highlight group exists when
the LspDetach handler is invoked. The LspDetach handler is used
to clean up any lsp highlights that were enabled by CursorHold
if the LSP is stopped or crashed.

* Add diff to treesitter's ensure_installed languages (nvim-lua#908)

* Added github copilot

* Added Java plugin

* custom plugins

* Just pushing it

* Just pushing it
