Update some dependencies

[tmpolaczyk]

What does it do?

Updates some dependencies to fix warnings about remove_dir_all and enumflags2. chrono and time are also updated, but that doesn't fix anything.

Is there something left for follow-up PRs?

Getting rid of the chrono dependency would be nice as that issues some false positives regarding to the time crate.

Your changes duplicate the syn dependency, can you fix that?

[tmpolaczyk]

@librelois yeah, that's unfortunate, but the only version of enumflags2 that has not been yanked is using syn 2: https://crates.io/crates/enumflags2/versions

This is the advisory that explains why it has been yanked, it probably doesn't affect us so I could remove that upgrade from this PR:

GHSA-qvc4-78gw-pv8p

But I believe that it is impossible to get all of the dependencies to upgrade from syn 1 to syn 2 simultaneously, so we will encounter this problem again in the future.

Updated with master. The syn dependency is already duplicated in master so that's no longer a problem for this PR.
