Bump globwalk dep to 0.9

[Gilnaa]

Bumps globwalk to version 0.9, mostly to get rid of bitflags 1.* transitive dependecy. (see Gilnaa/globwalk#34)

[Gilnaa]

It looks like ignore 0.4.21 has a much higher MSRV due to the new use of OnceLock. (available since Rust 1.70.0)
This doesn't look a regression that is related to this PR, (this can be reproduced by checking-out an older version of globwalk and running cargo +1.65.0 check).

Not sure what to make of it, honestly.

It's possible to explicitly mention ignore = "<=0.4.20" in tera's Cargo.toml, and it would technically make this test pass, but will limit tera's users to an old version of ignore until the constraint is removed; possibly causing conflicts with other crates.
Is there a best-practice I'm missing?

It's the problem of having a MSRV, in practice it can change at any point without a direct dependency update :/
In practice I think I will just wait for v2 to upgrade
