* lisp/progmodes/ruby-mode.el (ruby-smie-rules): Check for ':' and
'=>' as previous tokens, and handle symbols ending with ':' to
properly indent keyword argument arrays and hashes when
ruby-bracketed-args-indent is nil.
* lisp/progmodes/ruby-ts-mode.el (ruby-ts--parent-call-or-bol):
Handle arrays/hashes that are children of 'pair' nodes (keyword
arguments) to ensure consistent indentation.
* test/lisp/progmodes/ruby-mode-resources/ruby-bracketed-args-indent.rb:
Add test cases for keyword argument arrays and hashes with both
symbol-colon and hash-rocket syntax.
When ruby-bracketed-args-indent is nil, arrays and hashes used as
keyword argument values now indent by ruby-indent-level from the
line start, matching the documented behavior and fixing inconsistent
indentation (bug#74517).
