chore(*): replace concurrently and lerna with npm-run-all2 (#488)

This pull request removes the use of Lerna from the project and updates
the build and release workflow to rely solely on npm workspaces and
`npm-run-all2`. It also updates scripts and documentation to reflect
these changes, simplifies the build and test process, and replaces the
use of `concurrently` with `npm-run-all2`.

**Removal of Lerna and migration to npm workspaces:**

* Removed `lerna.json` and all references to Lerna from configuration
files and documentation, fully migrating the monorepo management to npm
workspaces.

**Build and release workflow updates:**

workflow to use npm workspaces and new script names, replacing
Lerna-based commands with npm and `npm-run-all2`.
