Bad interaction with bracket colorization: keywords are colorized inside identifiers

[julesjacobs]

When bracket colorization is turned on ("editor.bracketPairColorization.enabled": true), the match and end keywords are colored inside identifiers. This behaviour does not happen in e.g. Ruby where begin ... end is used to delimit blocks.

Seems to be related to a new feature in VSCode: colorized brackets. Made a pull request that I think solves the issue.
