Pin the Claude entry that exists rather than the one that used to

The dock shipped a pin for claude-desktop, and the application it names has
since been repackaged: the entry is com.anthropic.Claude now, and only the
binary kept the old name. A pin that resolves to nothing does not announce
itself -- the dock simply has one fewer icon than the settings say it should.

Found by the dock pins contract, which exists for exactly this and had been
passing until the application updated underneath it.
