gnu: oniguruma: Move to (gnu packages regex).

Authors were parsed from git history with the following command:

    git log --all --grep="gnu:.*oniguruma" \
    --pretty=format:";;; Copyright © %as %aN <%aE>"

* gnu/packages/textutils.scm (oniguruma): Move from here ...
* gnu/packages/regex.scm: ... to here.

* gnu/packages/admin.scm: Replace (gnu packages textutils) with (gnu
packages regex).
* gnu/packages/codex.scm: Likewise.
* gnu/packages/php.scm: Likewise.
* gnu/packages/rust-apps.scm: Likewise.
* gnu/packages/rust-sources.scm: Likewise.

* gnu/packages/machine-learning.scm: Remove (gnu packages textutils) to
resolve import warning.

* gnu/packages/web.scm: Adding (gnu packages regex) introduces import
warning, selecting just utf8proc from (gnu packages textutils) breaks
build.

* gnu/packages/textutils.scm: Add (guix deprecation).
