dependencies.py: use Enum rather than StrEnum for DependencyKind

StrEnum is only supported in Python versions 3.11 and
newer. Gentoolkit should not require >=3.11, so DependencyKind will
use the regular Enum feature instead.

The difference between StrEnum and Enum is that StrEnum members are
strings and can generally be used in place of strings in APIs
expecting string input. Non-StrEnum members are not strings, but you
can get members values by accessing their value field (DependencyKind.DEPEND.value).
