Null-ls deprecation

[BitInByte]

Null-ls get archived by the amazing @jose-elias-alvarez, you can follow the issue of the archived here: Null-ls archive issue

Potential alternatives:
Formatting:

1. conform.nvim
2. formatter.nvim

Lint:

1. nvim-lint

Package Manager:

1. mason-tool-installer.nvim

On the begin might gonna skip the package manager and install the linters and formatters manually from mason. The number 1) on each list is the one that more sense makes for this config.

Added a new commit ad4144b with the removal of the null-ls and addition of conform and nvim lint to the config. Missing the management of the formatters and linters automatically.
