* nongnu/packages/game-client.scm (heroic-client)[arguments]<#:phases>: Add
fix-desktop-file phase to set the "Exec" line to "heroic" to run the correct
binary.  Remove setting the full store path in the .desktop file in the
setup-cwd phase.  Delete the patch-dot-desktop-files phase (not needed).

The choice of fonts here is arbitrary, chosen as the google-noto set has fonts
for emoji and Chinese/Japanese/Korean and related scripts.  This fixes missing
emoji and characters from these languages in the Steam interface.  It would be
better to be able to use the font configuration and fonts from the host system
in the container, though.

* nongnu/packages/game-client.scm (steam-client-libs): Add font-google-noto,
font-google-noto-emoji, font-google-noto-sans-cjk, font-google-noto-serif-cjk.

* nongnu/packages/game-client.scm (heroic-client): Fix synopsis to satisfy
guix lint.

Most entries were unneeded or didn't make sense (trying to wrap the
libraries).

* nongnu/packages/game-client.scm (heroic-client)[arguments]<#:wrapper-plan>:
Remove unneeded entries.

* nongnu/packages/game-client.scm (heroic-client): Update to 2.15.2.

* nongnu/packages/game-client.scm (heroic-client)[arguments]<#:wrapper-plan>:
Add the path for heroic to its wrapper-plan.
<#:phases>: Remove wrap-where-patchelf-does-not-work phase as it is no longer
needed.

Fixes #355.

* nongnu/packages/steam-client.scm (steam-client-libs): Replace gcc with
gcc-14.

It is unclear why steam failed to build post-core-updates merge in Guix, with
errors like:

In guix/build/utils.scm:
    761:4  0 (alist-cons-after patch-dot-desktop-files # #<procedur?> ?)

guix/build/utils.scm:761:4: In procedure alist-cons-after:
Throw to key `match-error' with args `("match" "no matching pattern" ())'.

The fix is to reorder and rename some phases which apparently don't exist.

* nongnu/packages/game-client.scm (steam-client)[arguments]<phases>: Reorder
the deletion of 'patch-dot-desktop-files to after 'patch-desktop-file (which
tried to add after this now deleted phases).  Change the 'post-install phase
to add after 'install ('install-binaries doesn't exist').

* nongnu/packages/game-client.scm (heroic-client): Update to 2.14.1.

* nongnu/packages/nvidia.scm (%nvidia-environment-variable-regexps): New
variable.
* nongnu/packages/game-client.scm (steam-nvidia-container)
(heroic-nvidia-container): Use it.
