Bump riot to >= 0.0.9 in minttea.opam

[chshersh]

The version is bumped inside dune-project but not in the minttea.opam file.

Because of this, when pinning the latest version of minttea from GitHub, I see the following error (which was very confusing to debug because it doesn't say which package has this strict constraint):

❯ opam switch create .
Package github_tui does not exist, create as a NEW package? [Y/n] y
The following additional pinnings are required by github_tui.~dev:
  - minttea.dev at git+https://github.com/leostera/minttea
  - riot.dev at git+https://github.com/riot-ml/riot
  - shape-the-term.dev at git+https://github.com/jmcavanillas/shape-the-term
Pin and install them? [Y/n] y
[minttea.dev] synchronised (no changes)
minttea is now pinned to git+https://github.com/leostera/minttea (version dev)
[riot.dev] synchronised (no changes)

Unfortunately, even with this fix it doesn't compile. Not sure why because the OCaml code in minttea looks legit.

[ERROR] The compilation of minttea.dev failed at "dune build -p minttea -j 7 @install".
