This is not a bug.  Emacs 29 comes with major modes for TOML files and
for Dockerfiles, and those new major modes require that you build
Emacs with the tree-sitter library (and install the corresponding
parser grammar libraries).  If you don't want to do that, you can
instead customize auto-mode-alist to make Emacs use Fundamental mode
(or any other mode you like) for these two file types.
