Update dependency bounds to allow building with GHC 9.8

[LaurentRDC]

This is a small PR to prepare Hakyll to be buildable with GHC 9.8.

In practice, pandoc isn't buildable yet with GHC 9.8; however, you can build hakyll with GHC 9.8.1 using the following cabal.project file:

packages: *.cabal

allow-newer: unicode-collation:base,
             typst-symbols:text,
             jira-wiki-markup:text,
             gridtables:text,

In the meantime, I have created PRs in other repositories to make pandoc buildable with GHC 9.8:

• https://github.com/jgm/unicode-collation/pull/14
• https://github.com/jgm/typst-symbols/pull/1
• https://github.com/tarleb/jira-wiki-markup/pull/22
• https://github.com/quarto-dev/gridtables/pull/11
