docs: Quote PWD in window title example (#2539) 

Quote expansion of $PWD to prevent word-splitting of its value, which
gives an incorrect result if there is a single space and an error
message if there is more than one space:

    ❯ basename /tmp/foo
    foo

    ❯ basename /tmp/foo bar
    foo

    ❯ basename /tmp/foo bar baz
    basename: extra operand ‘baz’
    Try 'basename --help' for more information.
