Can't reference SwiftGodot using .package(url: … from: 0.21.0

[PadraigK]

If I add SwiftGodot as a dependency pointing to branch: "main" everything works, but if I use the .package(url: "https://github.com/migueldeicaza/SwiftGodot", from: "0.21.0") syntax, then swift package update fails with:

> error: the target 'SwiftGodot' in product 'SwiftGodot' contains unsafe build flags

I reviewed the commits between the 0.21.0 tag and main and they do not change anything in the Package file. I looked into it and it turns out that Swift PM handles these two differently.

This means that we will either need to get rid of the unsafe flags in the Swift Godot package, or we will not be able to use release tags.

The unsafe flags, for reference:

.unsafeFlags([
    "-Xlinker", "-undefined",
    "-Xlinker", "dynamic_lookup",
])

I've been running into this as well, and I believe I documented it in an earlier issue (#52, I think?). A workaround I've been using is referencing the commit hash of the tag in question, rather than the tag itself

Right, that works, but we ideally ought to have standard release conventions, so I think it's important to figure this out.

This is tentatively working now with the suggested approach
