Test failure on GHC 9.8

[roberth]

We've encountered a test failure when building and testing on GHC 9.8.1:

The failures seem quite innocent, if the change from Symbol:c:: to Symbol:c: is acceptable.

Failures:

This is already fixed in hiedb 0.6.0.0

I believe the issue is that Show instance of Symbol was changed right before 0.5.0.1 was released (https://github.com/wz1000/HieDb/commit/6aba7448a8041e27e14b26fb54c7044e92081c43)

But the tests (and CI) was updated 2 commits after that (https://github.com/wz1000/HieDb/pull/59).
