Fix ionide#209: Remove (* *) from brackets config

language-configuration.json lets you define various pairs of brackets
and braces for autoclosing, surrounding selected text with characters,
and, as it turns out, dictating which brackets get colorized by
the native bracket colorizer.

As far as I can tell, putting the block comment brackets inside the
`brackets` field is pointless. We color our comments green anyway,
so the colors don't show anyway. It is true that F# provides
support for nested comment blocks, but we aren't taking advantage
of the color feature anyway (and I'm unsure if it's even possible
to do so).

The block comments should, however, remain in the other fields
that control autocomplete and surrounding selected text.
