Improve formatting for empty tuple types (#​11884 by @​sosukesuzuki)

// Input
type Foo =
  Foooooooooooooooooooooooooooooooooooooooooooooooooooooooooo extends []
    ? Foo3
    : Foo4;

// Prettier 2.5.0
type Foo = Foooooooooooooooooooooooooooooooooooooooooooooooooooooooooo extends [

]
  ? Foo3
  : Foo4;

// Prettier 2.5.0 (tailingCommma = all)
// Invalid TypeScript code
type Foo = Foooooooooooooooooooooooooooooooooooooooooooooooooooooooooo extends [
  ,
]
  ? Foo3
  : Foo4;

// Prettier 2.5.1
type Foo =
  Foooooooooooooooooooooooooooooooooooooooooooooooooooooooooo extends []
    ? Foo3
    : Foo4;

Fix compatibility with Jest inline snapshot test (#​11892 by @​fisker)

A internal change in Prettier@​v2.5.0 accidentally breaks the Jest inline snapshot test.

Support Glimmer's named blocks (#​11899 by @​duailibe)

Prettier already supported this feature, but it converted empty named blocks to self-closing, which is not supported by the Glimmer compiler.

See: Glimmer's named blocks.

// Input
<Component>
  <:named></:named>
</Component>

// Prettier 2.5.0
<Component>
  <:named />
</Component>

// Prettier 2.5.1
<Component>
  <:named></:named>
</Component>
