For tagged release there is no need for commit and revision, I'll remove
them and apply the part of the patch related to guile-scheme-json-rpc
version update as separate commit.

auto tools is already provided by gnu-build-system, no need to provide
them one more time.  I don't see any texi docs, so probably texinfo is
not needed.  Also guile-3.0 in native (build host side) inputs also not
needed.  Removed.

It's better to use (assoc-ref inputs ...) here, because
#$guile-scheme-json-rpc will hardcode the exact package and if someone
will try to inherit from guile-lsp-server and override
guile-scheme-json-rpc input, it won't make a desired effect and
hardcoded version of guile-scheme-json-rpc will be used.

Also, guile-lsp-server executable doesn't run, it's very likely that
other required dependencies are missing here in the deps variable.

For standalone programs like guile-lsp-server, where we manually
construct GUILE_LOAD_PATH it's not needed to propagate dependencies in
the profile, where package is installed.  It should be just inputs.

Applied first part of the patch, pushed as
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=56667ee55c

Please update the guile-lsp-server package definition to make it work
(right now package builds, but executable fails to run).

P.S. Thanks to Giacomo for spinning up this thread!
