dockerfile.xml: Use `bash` syntax for shell form of commands (!263) · Merge requests · Frameworks / Syntax Highlighting Engine

The source project of this merge request has been removed.

Also,

add missed AS keyword
recognize parser directives (see https://docs.docker.com/engine/reference/builder/#syntax)
recognize command options

P.S. @cullmann nowadays I'm a bit out of the Kate development process and dunno how to easily fix the hl tests... tests are filed for this MR now ;-(
