feature: integration with Jenkinsfile

[idelice]

Did you check the docs?

• I have read all the LazyVim docs

Is your feature request related to a problem? Please describe.

I have no LSP attached to a Jenkinsfile, nor treesitter or cmp.

Neovim sees it as normal text.

Describe the solution you'd like

I would like an integration that enables treesitter parsing, cmp and linter for Jenkinfiles

Describe alternatives you've considered

n/a

Looks like a new parser for groovy was merged around two (2) months ago nvim-treesitter/nvim-treesitter#5957

To activate it, maybe adding it to ensure_installed would be enough.

(this will only address the treesitter parser part of the request)
