* fix: Eliminate spurious biome schema version errors on "biome ci" command
Stronger fix for commit dd9d79d2d6
Apply the BKM at https://biomejs.dev/internals/versioning/
that recommends pinning a specific version of biome
(current version of package-lock.json uses 2.4.4,
which was previously installed with ^2.3.10)
Otherwise, if npm is allowed to upgrade at its discretion,
project will have to continually chase the latest schema version.
The specific error that is fixed when "biome ci" is invoked:
```
ℹ The configuration schema version does not match the CLI version (local installed version)
> 2 │ "$schema": "https://biomejs.dev/schemas/2.3.14/schema.json",
│ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
package-lock.json is also updated to reflect the package.json change.

* fix: clean up unrelated package-lock.json changes
Revert unrelated peer/encoding metadata changes that were
artifacts of a different npm version, keeping only the
biome version pin change.
