[FR]: support multiple targets, in line with cli api

[jackvincentnz]

What is the current behavior?

Currently we can only pass a single target string to the rule.

Describe the feature

The cli supports passing multiple targets and will bundle based on the minimum support needed.

See the example here: https://esbuild.github.io/api/#target

I think it should be a simple fix to support passing an array of target strings rather than a single string via the rule.

Thanks for the suggestion. If it is supported by the CLI then we shouldn't prevent it with the rule API. Added this to the 1.0 milestone for this rule set.
