Joshua Richter a2ea711c29 fix(grammar): stop the Swift try-bang entry shifting past its own type ...

scanner.c line 131 shifts a literal 1UL by 32 to build the entry that
suppresses the bang of a try!. unsigned long is 64 bits on Linux and
macOS but 32 bits on Windows, so there the shift count equals the width
of the type, which is undefined.

1ULL is 64 bits on every target this project builds for.

Nothing reports it today. The expression is a compile-time constant, so
no sanitizer sees it run, and Makefile.cbm:719 builds vendored grammars
with -w, which switches off -Wshift-count-overflow.

Upstream tree-sitter-swift made the same change in 6ab8d1d74ebd, after
the commit this grammar is pinned to.
