fix: look for yarn pnp when looking for eslint projdir

* Fix texlab GetProjectRoot

* Fix indents in texlab#GetProjectRoot

* Prevent texlab from starting on every tex file

* Update texlab Vader tests

* Fix GetProjectRoot to return parent of .git

Previously, the function returned `../.git/`. We want the function to return the parent directory above that as the project root. This should help pass Vader tests.

+### 5.iii. How can I use ALE and coc.nvim together?
+
+[coc.nvim](https://github.com/neoclide/coc.nvim) is a popular Vim plugin written
+in TypeScript and dependent on the [npm](https://www.npmjs.com/) ecosystem for
+providing full IDE features to Vim. Both ALE and coc.nvim implement
+[Language Server Protocol](https://microsoft.github.io/language-server-protocol/)
+(LSP) clients for supporting diagnostics (linting with a live server), and other
+features like auto-completion, and others listed above.
+
+ALE is primarily focused on integrating with external programs through virtually
+any means, provided the plugin remains almost entirely written in Vim script.
+coc.nvim is primarily focused on bringing IDE features to Vim. If you want to
+run external programs on your files to check for errors, and also use the most
+advanced IDE features, you might want to use both plugins at the same time.
+
+The easiest way to get both plugins to work together is to configure coc.nvim to
+send diagnostics to ALE, so ALE controls how all problems are presented to you,
+and to disable all LSP features in ALE, so ALE doesn't try to provide LSP
+features already provided by coc.nvim, such as auto-completion.
+
+1. Open your coc.nvim configuration file with `:CocConfig` and add
+   `"diagnostic.displayByAle": true` to your settings.
+2. Add `let g:ale_disable_lsp = 1` to your vimrc file, before plugins are
+   loaded.
+
+You can also use `b:ale_disable_lsp` in your ftplugin files to enable or disable
+LSP features in ALE for different filetypes. After you configure coc.nvim and
+ALE this way, you can further configure how problems appear to you by using all
+of the settings mentioned in ALE's help file, including how often diagnostics
+are requested. See `:help ale-lint`.
+
+The integration between ALE and coc.nvim works using an API ALE offers for
+letting any other plugin integrate with ALE. If you are interested in writing a
+similar integration, see `:help ale-lint-other-sources`.
