Use compact-no-array style for @InlineMe annotations - #2366

Suggestions by the InlineMeSuggester always use the array syntax for import annotations even when only one import is listed.

This clashes with checkstyle's AnnotationUseStyleCheck check which uses COMPACT_NO_ARRAY style per default and disallows single-value arrays. Note that the proposed style would also work with the two other checkstyle options.

Example:

- @InlineMe(replacement = "REPLACEMENT", "imports = {"java.time.Duration"})
+ @InlineMe(replacement = "REPLACEMENT", "imports = "java.time.Duration")

Note that this is a more nitty suggestion -- fine to drop this if the other style is preferred. But I believe this would reduce friction for consumers using checkstyle.
