Error formatting endless method definitions

[JosefuMealsom]

Seems to be an error with formatting endless method definitions in ruby as outlined here: https://rubyreferences.github.io/rubychanges/3.0.html#endless-method-definition

Example code:

class MyAwesomeClass
  def my_awesome_method = 123
end

PRs are welcome for this, I am not using Ruby for my daily work anymore so won't have time to fix it sorry

[JosefuMealsom]

@gingermusketeer thats cool. I've found the issue, but fitting that into the current code might take a little work. Would you be available to review the changes when I get around to it?

[gingermusketeer]

@JosefuMealsom Yep I can take a look :)

[manuraj17]

@JosefuMealsom @gingermusketeer Does this PR https://github.com/ruby-formatter/rufo/pull/274 close this issue?
