* refactor(linters): add prefer-coerce-array rule
Refs #45217
`x ?? []` and `coerceArray(x)` say the same thing, but only the second
one is searchable and consistent. The rule flags a `??` whose default is
a bare `[]` literal; a non-empty default or an asserted `([] as Foo[])`
still passes.
Applying it across `lib/` surfaced three spots the helper cannot cover,
which keep `?? []` with a disable comment or a narrower fix:
- `package-files.ts` destructures a tuple, which `coerceArray()` widens
- `generate.spec.ts` defaults `matchAll()`, an iterator rather than an array
- `mise/upgradeable-tooling.ts` declares a `Record` return, so its
`?? []` fallback was wrong to begin with and becomes `coerceObject()`
* refactor(platform/github): hoist the GHE version header lookup
`Object.entries(...).find()` returns a tuple, and defaulting it with
`?? []` only to destructure the second element reads as an array
default when it is not one. Name the found entry instead, which drops
the `?? []` rather than routing a tuple through `coerceArray()`.
As `fileName` makes more sense (as it's not always a lock file we're
updating).
Also, if you set `fileName`, it would never actually output the
filename.
This renames the usages of `lockFile` to `fileName`.

When using Vendir with Git repositories, we do not currently provide
authentication via Host Rules, which means we cannot access private
repositories.
Instead, we should set these, so they can be used by `vendir sync` to
authenticate to private repos.
