emacs29: update to 29.2.

* Changes in Emacs 29.2

This is a bug-fix release with no new features.

* Changes in Specialized Modes and Packages in Emacs 29.2

** Tramp

*** New user option 'tramp-show-ad-hoc-proxies'.
When non-nil, ad-hoc definitions are kept in remote file names instead
of showing the shortcuts.

* Incompatible Lisp Changes in Emacs 29.2

** 'with-sqlite-transaction' rolls back changes if its BODY fails.
If the BODY of the macro signals an error, or committing the results
of the transaction fails, the changes will now be rolled back.
