* feat: add experimental use-inline-specifiers-lockfile-format
* fix(lockfile-file): check importers key for shared lockfile format
The `convertFromLockfileFileMutable` function reverts changes from
`normalizeLockfile` when not using the shared lockfile format.
- The non-shared lockfile format puts fields like `specifiers`,
`dependencies`, `devDependencies`, `optionalDependencies`, and
`dependenciesMeta` on the root of the lockfile. This is typically
the case for a repo not using pnpm workspaces.
- The shared lockfile format puts these under a `importers` block
scoped by a path.
The `use-inline-specifiers-lockfile-format` feature flag removes the
`specifiers` block in favor of putting each specifier next to the
resolved version within each `dependencies`, `devDependencies`, etc
block.
This means the `convertFromLockfileFileMutable` function can no longer
check for `specifiers` to detect the whether the "shared" format is
used. @zkochan suggested checking for `importers` instead, which should
have the same effect.
