Add code completion support for the --start-interval HEALTHCHECK flag

[prikhi]

The HEALTHCHECK command supports a --start-interval=<duration> flag that controls the check's interval during the specified --start-period:

Hello, @prikhi. What feature or features are you looking for with regards to this new flag?

[prikhi]

The autocompletion doesn't include it & if I put it in manually I get an Unknown flag: start-interval error

Thank you for clarifying what features you are interested in.

The false positive in the linter is tracked by rcjsuen/dockerfile-utils#115. I will make sure support for code completion is implemented as well.
