Expressions inside string templates

[mbtools]

Highlighting of formatting options inside string templates does not work.

test = |Hello { sy-uname ALIGN = RIGHT }. Today is { sy-datum DATE = ISO }|.

Here are the missing parts but I'm not sure how to integrate them into the grammar 🤷

	<dict>
		<key>match</key>
		<string>(?ix)(?&lt;=\s)(align|alpha|case|country|currency|date|decimals|exponent|number|pad|sign|style|time|timestamp|timezone|width|xsd|zero)(?=\s|=)</string>
		<key>name</key>
		<string>name.property.stringtemplate.abap</string>
