refactor(dap): split dap and dap_ui integrations

[igorlfs]

This Pull Request makes 3 changes to the nvim-dap integration:

1. Splits the dap and dap_ui integrations. Rationale: there's no need for both plugins to share a integration. In fact, that's the only integration that contains multiple plugins.
2. Adds a missing highlight group to the nvim-dap integration
3. Removes a misguided comment about enabling the nvim-dap integration

I'm not sure why, but the integrations are not enabled by default. Did I forget something?

Hey, thanks for your pull request. There are some things you forgot, you should:

• Update integration types in lua/catppuccin/types.lua
• Update selene integration
• ...

I'm busy right now, will take a look a bit later.

I'm not sure why, but the integrations are not enabled by default.

All integrations are disabled by default, only some of them are enabled in default_options here.

I wonder why 🤔

Other than that, everything looks nice, @igorlfs can I merge this?

1. Need to add backwards compatibility because we're no longer 0ver (We're pretty much against unnecessary breaking changes)

dap = { enabled = true, dap_ui = true }

should be auto converted to

dap = true, dap_ui = true

Something like this would work (Please verify very carefully):

if O.integrations.dap.enabled and O.integrations.dap.dap_ui ~= nil then
  O.integrations.dap_ui = O.integrations.dap.dap_ui
end

2. Integrations are enabled by default if they're known to be well tested.

Hey! Thanks for merging! I've been kinda busy lately, so I couldn't catch up!
