Bump Scalafmt

[sequencer]

Type of issue: Feature Request

Old Scalafmt will has some parsing issues, see #3992. We need to upgrade it, but seems it is not compatible, we may need to reformat the entire code base...

Is your feature request related to a problem? Please describe.

Here is a straightforward change to scalafmt config, but seems new version of scalafmt is more aggressive.

It's a little annoying to reformat, but we can do it. We'll probably want to apply the reformatting to all branches we may backport to as well (6.x and 5.x definitely, probably 3.6.x as well).
