[swiftsrc2cpg] Update swiftastgen to 0.3.3 (#5647)

Brings in joernio/SwiftAstGen#18 so we can finally run it on larger projects on certain Linux distributions where the small default musl stack size resulted in seg faults.

See: https://wiki.musl-libc.org/functional-differences-from-glibc.html#Thread-stack-size
