Release v5.0.9 (#3597)

* Update all grammars

* Update atom-language-clean grammar to match

* Don't update reason grammer

There seems to be a problem with the 1.3.5 release in that the conversion isn't producing a reason entry so doesn't match whats in grammar.yml

* Bump version to 5.0.9

* Update grammars

* Don't update javascript grammar

The current grammar has a known issue and is pending the fix in https://github.com/atom/language-javascript/pull/497

 To add support for a new language:
 
-0. Add an entry for your language to [`languages.yml`][languages].
-0. Add a grammar for your language. Please only add grammars that have a license that permits redistribution.
-  0. Add your grammar as a submodule: `git submodule add https://github.com/JaneSmith/MyGrammar vendor/grammars/MyGrammar`.
-  0. Add your grammar to [`grammars.yml`][grammars] by running `script/convert-grammars --add vendor/grammars/MyGrammar`.
-  0. Download the license for the grammar: `script/licensed`. Be careful to only commit the file for the new grammar, as this script may update licenses for other grammars as well.
-0. Add samples for your language to the [samples directory][samples] in the correct subdirectory.

 The Language stats bar displays languages percentages for the files in the repository.

+### There's a problem with the syntax highlighting of a file
+
+Linguist detects the language of a file but the actual syntax-highlighting is powered by a set of language grammars which are included in this project as a set of submodules [and may be found here](https://github.com/github/linguist/blob/master/vendor/README.md).
+
+If you experience an issue with the syntax-highlighting on GitHub, **please report the issue to the upstream grammar repository, not here.** Grammars are updated every time we build the Linguist gem and so upstream bug fixes are automatically incorporated as they are fixed.

 ### Using gitattributes

+#### Vendored code
+
 Checking code you didn't write, such as JavaScript libraries, into your git repo is a common practice, but this often inflates your project's language stats and may even cause your project to be labeled as another language. By default, Linguist treats all of the paths defined in [lib/linguist/vendor.yml](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml) as vendored and therefore doesn't include them in the language statistics for a repository.

-    Indeed, this file defines a notion of permutation based on
-    multisets (there exists a permutation between two lists iff every
-    elements have the same multiplicity in the two lists) which
-    requires a more complex apparatus (the equipment of the domain
-    with a decidable equality) than [Permutation] in [Permutation.v].
-
-    The relation between the two relations are in lemma
-    [permutation_Permutation].
-
-    File [Permutation] concerns Leibniz equality : it shows in particular
-    that [List.Permutation] and [permutation] are equivalent in this context.
