editors/sly: Update to latest commit (dated 2024/08/09)

Updates:

• Prevent ‘C-h m’ from breaking in Sly debugger buffers.
• Unbreak odd non-SLY uses of slynk/indentation system.
• mrepl: Fix a bug on SBCL.
• Emit :company-kind in Sly's flex CAPF (allows completion frameworks to show type icons).
• Make sly-simple-completions behave more like vanilla.
• Add option to control if we replace SLIME on load.

The SLY contribs in the ports tree have not been bumped as this new
version does not change the interface to them, so they don't need
recompilation.

This is a maintainer update (olce.freebsd.ports@certner.fr).
