Add lockfiles, and update parcel/core

[michaellisitsa]

• [Add] Lockfile added. This prevented dependabots from working. This is an issue since 20th Jan 2025 per https://github.blog/changelog/2025-01-20-dependabot-will-no-longer-support-npm-v6/. Although we don't specify an npm version, because lock files were not included, npm failed. see related issue [CI] Warning: Dependabot does not support your npm version open-telemetry/opentelemetry.io#6007 (comment).
• [bump] Update parcel/core to v12.12.0 to match all other parcel versions
• [Add] Add parcel/config-default as explicit dependency as we use this in the .parcelrc config. This previously worked when the repository was at v2.9.3.

Outstanding:

• merge conflict
• Running npm run compile-interactive has issues Cannot find module "@parcel/config-default", did you mean "@parcel/bundler-default"?

Now ready to review. Manual testing completed.

Running npm run compile-interactive has issues Cannot find module "@parcel/config-default", did you mean "@parcel/bundler-default"?

We are using config-default inside of the .parcelrc file, but it is not an explicit import. See similar issue parcel-bundler/parcel#5603 (comment)
