Remove require_trailing_commas

[masa-tokyo]

Hello mono-san,
Thank you for the great package :)
I'd be glad if you consider removing the lint rule require_trailing_commas from the list.

As Dart 3.7 introduced the new format style, the rule conflicts the formatted code in some cases.
For example, a function with positional parameters that contain list literals or function literals (a famous example is flutter_hooks useEffect) is cautioned by the rule. Please take a look at the sample code for details.

FYI:

• This is argued in the issue here.
• Another package very_good_analysis will remove the rule also.

Since you can disable any rules for each project, I initially judged that it might be fine to just leave it as is and observe the situation.

The conflict issue might be resolved with a fix to either the formatter or require_trailing_commas. However, since the formatter in Dart 3.7 has a feature equivalent to require_trailing_commas (adding commas as needed), it might be acceptable to proceed without require_trailing_commas.

I was hesitating about whether to address this after the discussion in that area is settled, but since it seems like it will take some time, it might be best to go ahead and remove require_trailing_commas first and then add any necessary reasons later 🤔
