There's a dedicated type for a mapping from "string to variant" in
GVariantDict. Use it instead of rolling our own with GHashTable.
The advantage here is improved ergonomics from the C side; e.g.
we can directly pass C strings for values and have the variant
allocated internally.

But more importantly, this is prep for oxidizing things here because
we can pass GVariantDict to/from Rust easily, not so with
GHashTable.

Skipping CI for Draft Pull Request.
If you want CI signal for your change, please convert it to an actual PR.
You can still manually trigger a test run with /test all

rpmostree_context_get_rpmmd_repo_commit_metadata (self->corectx));
g_variant_dict_insert_value (
self->metadata, "rpmostree.rpmmd-repos",
rpmostree_context_get_rpmmd_repo_commit_metadata (self->corectx));

Aren't we double referencing here?

LGTM. CI failure might be related, though don't see offhand where the issue is.

Yeah, the CI failure is definitely related, but I don't yet understand it either. Not critical, will come back to this some point later.
