[bug#56455] gnu: Drop emacs-transient, emacs-project input from four packages

[Jorge P. de Morais Neto]

Hi.  I apologize for any mistakes and welcome feedback.  This is my
first patch to Guix; let's hope that many others will follow!  I see low
hanging fruits: including the several other Emacs packages still
unnecessarily pulling emacs-transient, emacs-project and other Elisp
libraries that are now builtin.

I have been using these modified packages.  I have also checked this
patch with ~guix lint~ and ~guix build --check~.  The four packages
build well; the only warning messages were:

In git-timemachine-completing-read-fn:
git-timemachine.el:101:8: Warning: docstring wider than 80 characters

In git-timemachine--find-new-current-line:
git-timemachine.el:259:8: Warning: docstring wider than 80 characters

In git-timemachine--get-cursor-position:
git-timemachine.el:294:8: Warning: docstring wider than 80 characters

In git-timemachine--set-cursor-position:
git-timemachine.el:300:8: Warning: docstring wider than 80 characters
git-timemachine.el:347:1: Warning: ‘define-transient-command’ is an obsolete
    alias (as of Transient 0.3.0); use ‘transient-define-prefix’ instead.

In end of data:
git-timemachine.el:247:19: Warning: the function ‘erm-reset-buffer’ is not
    known to be defined.

geiser-autodoc.el:69:12: Warning: ‘eldoc-message’ is an obsolete function (as
    of eldoc-1.1.0); use ‘eldoc-documentation-functions’ instead.

git-commit-pkg.el:1:2: Warning: the function ‘define-package’ is not known to
    be defined.

Subject: [PATCH] gnu: Drop emacs-transient, emacs-project input from four
 packages

Drop emacs-transient (and emacs-project) propagated input from:
- emacs-git-timemachine
- emacs-ytdl
- emacs-geiser
- emacs-magit

I use Guix package manager (manually installed) atop Debian bullseye.  My
Emacs is from Guix package emacs-next with a package transformation option to
pull from current Git master.  When trying to use the new emoji commands on
the "C-x 8e" prefix, I got an error message about transient.  I solved it by
modifying Guix recipes to not pull emacs-transient as propagated input of some
Emacs packages I installed via Guix.

Guix packages Emacs 28.1 and emacs-next 29.0.50, and both have Transient
built-in.  Therefore, pulling transient external package it as propagated
input of other packages is wasteful redundancy, and, worse, causes errors.

>From emacs-geiser also drop emacs-project (also builtin on Emacs 28.1).

For emacs-ytdl also add the required emacs-dash dependency.

See email message ID 87sfnhalvo.fsf@disr.it on guix-devel mailing list.

Several other unnecessary dependencies on builtin Emacs libraries (including
transient and project) probably remain on emacs-xyz.
