Code formatting support

[NatoBoram]

The new Phoenix LiveView release supports a new .html.heex and ~H template engine, which deprecates .eex, .leex and ~L. It would be nice to have auto-formatting support for these.

• heex templates are not supported adamzapasnik/prettier-plugin-eex#71
• Support for .html.heex beautifier/js-beautify#1964
• HTML indention does not work correctly in eex and leex files elixir-lsp/vscode-elixir-ls#162
• ~H sigil support elixir-lsp/vscode-elixir-ls#201
• Feature: Good support for eex/leex files elixir-lsp/vscode-elixir-ls#98
• Add ~H support elixir-lsp/vscode-elixir-ls#193
• Add Phoenix.LiveView.HTMLFormatter phoenix_live_view#1904
• Code formatting support #6
• Support for .html.heex prettier/prettier#12269

The formatting should happen as part of the regular Elixir tooling. :)
