Fix leading comments in mapped types with readonly (#​13427 by @​thorn0, @​sosukesuzuki)

// Input
type Type = {
  // comment
  readonly [key in Foo];
};

// Prettier 2.8.3
type Type = {
  readonly // comment
  [key in Foo];
};

// Prettier 2.8.4
type Type = {
  // comment
  readonly [key in Foo];

Group params in opening block statements (#​14067 by @​jamescdavis)

This is a follow-up to #​13930 to establish wrapping consistency between opening block statements and else blocks by
grouping params in opening blocks. This causes params to break to a new line together and not be split across lines
unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the
same as opening blocks.

Ignore files in .sl/ (#​14206 by @​bolinfest)

In Sapling SCM, .sl/ is the folder where it stores its state, analogous to .git/ in Git. It should be ignored in Prettier like the other SCM folders.

Recognize @satisfies in Closure-style type casts (#​14262 by @​fisker)
