Update the Materialize lexer (#978)

This introduces some additional keywords. I've also scripted this on our end hence the changes in formatting and encoding of certain characters in attribute values. This also includes: - Some tests - Updates to the README to call out the `--csrf-key` argument for chromad. Without it securecookie throws an error.

 If you edit some lexers and want to try it, open a shell in `cmd/chromad` and run:
 
 ```shell
-go run .
+go run . --csrf-key=securekey
 ```
