Update crate-git-revision to 0.0.9 (#1909)

### What

Bump the `crate-git-revision` build dependency of `soroban-sdk` from
0.0.6 to 0.0.9.

### Why

Keeps the build-time git revision tooling current with upstream
releases, picking up the fixes and improvements shipped between 0.0.6
and 0.0.9. The transitive 0.0.6 pull-in via `stellar-strkey` is retained
in the lockfile, so this only advances the version `soroban-sdk` builds
against directly.

### Known limitations

Because `0.0.x` releases aren't semver-compatible, the transitive
`^0.0.6` requirement keeps 0.0.6 in the lockfile alongside 0.0.9. A
one-line skip for the 0.0.6 duplicate was added to `deny.toml`
(mirroring the existing skips) so `cargo-deny`'s bans check passes, and
the fuzz `Cargo.lock` was regenerated.
