feat(manager/mise): add support for rustfs

[mnm364]

Changes

Adds rustfs (RustFS) to the set of mise tools that renovate can manage. RustFS is an Apache-2.0, S3-compatible object storage system written in Rust, published as GitHub releases at rustfs/rustfs. Tags follow semver (e.g. `1.0.0-beta.1`) so the default `GithubReleasesDatasource` works without an `extractVersion` override.

This pairs with jdx/mise#9530, which adds the corresponding `registry/rustfs.toml` (github backend). After both land, users can drop manual `# renovate:` overrides and rely on the registry name:

```toml
[tools]
rustfs = "1.0.0-beta.1"
```

How I've tested my work (please select one)

I have verified these changes via:

• Newly added/modified unit tests

`pnpm vitest run lib/modules/manager/mise/extract.spec.ts` and `pnpm vitest run lib/modules/manager/index.spec.ts` both pass.

We should be able to automagically support this through #42783 (there's an issue with the automated update of tool support we need to fix) but there shouldn't need to be any manual work for adding support 🤞🏼
