Textmate grammar support for indexed properties

[xorye]

For property keys that contain symbols like [ and #, the properties textmate grammar displays incorrect highlighting.

For example, for openshift.config-map-volumes[0].config-map-name, the property key is not highlighted in blue:

For properties that contain #:

Currently, the TextMate grammar assumes that property keys are only composed of: \/a-zA-Z0-9%_.-

WIP:

Should I keep the highlighting for the index, or change it back to the same colour as the rest of the property name (since this will be in vscode-microprofile).

Here is what I settled on. I used the default VSCode theme (Dark+) in this screenshot to avoid confusion regarding the colours:

Properties with square braces in their names have no special meaning in most implementations of MicroProfile Config as far I can tell, so it doesn't make sense to do specific highlighting. If this feature is helpful for Quarkus, we could maybe do it in vscode-quarkus.
