Update enumflags2 to non-yanked version (#1874)

* Update enumflags2 to non-yanked version
```
❯ cargo update -p enumflags2
    Updating crates.io index
    Updating enumflags2 v0.7.5 -> v0.7.7
    Updating enumflags2_derive v0.7.4 -> v0.7.7
    Updating proc-macro2 v1.0.47 -> v1.0.56
    Updating quote v1.0.21 -> v1.0.26
      Adding syn v2.0.15
```

Unfortunately this adds the syn v2 dependency for some platforms

* Updating dependencies is a valid label
* cargo deny: check more platforms
