Update dependency constraint to allow for liquid v5.4.0

[jekyllbot]

Hey there! 👋

I noticed that the constraint you have for liquid doesn't allow for the latest version to be used.

The constraint I found was ~> 4.0, and the latest version available is 5.4.0.

Can you look into updating that constraint so our users can use the latest and greatest version? Thanks! 💞

This issue has been automatically marked as stale because it has not been commented on for at least two months.

The resources of the Jekyll team are limited, and so we are asking for your help.

If this is a bug and you can still reproduce this error on the latest 3.x-stable or master/main branch, please reply with all of the information you have about it in order to keep the issue open.

If this is a feature request, please consider building it first as a plugin. Jekyll 3 introduced hooks which provide convenient access points throughout the Jekyll build pipeline whereby most needs can be fulfilled. If this is something that cannot be built as a plugin, then please provide more information about why in order to keep this issue open.

This issue will automatically be closed in two months if no further activity occurs. Thank you for all your contributions.
