Depends deprecated `autoload` package

[conao3]

Hi, when I use el-get on Emacs-29.0.50 and I get the below message on the Warnings buffer.

⛔ Warning (comp): el-get-core.el:25:11: Warning: Package autoload is deprecated

I don't know why el-get depends autoload but I just wanted to inform you about this.

The same happens to the Actions Emacs snapshot builds. All builds currently fail, because byte compilation is done with (setq byte-compile-error-on-warn t).

According to https://mail.gnu.org/r/emacs-devel/2022-09/msg00841.html, the replacement for autoload in Emacs 29 is loaddefs-gen.

EDIT: For Straight.el the topic is discussed here.
