feat: add run-script workspaces

- Add workspaces-related configs:
  - workspace: list of workspaces names/dir to filter for
  - workspaces: boolean value to enable/disable workspaces awareness
  - adds the proposed note in the docs of each of the commands
    that are not affected by these configs.
- Add workspaces support to `npm run-script`
  - add ability to serially run lifecycle scripts in workspaces
  - add ability to list scripts for all workspaces
  - add colors to `npm run` (no args) output

+### Workspaces support
+
+You may use the `workspace` or `workspaces` configs in order to run an
+arbitrary command from a package's `"scripts"` object in the context of the
+specified workspaces. If no `"command"` is provided, it will list the available
+scripts for each of these configured workspaces.

+   +-- b
+   |   `-- package.json
+   `-- c
+       `-- package.json
+```
+
+Assuming the workspace configuration is properly set up at the root level
+`package.json` file. e.g:
+
+```
+{
+    "workspaces": [ "./packages/*" ]
+}
+```
+
+And that each of the configured workspaces has a configured `test` script,
+we can run tests in all of them using the `workspaces` config:
+
+```
+npm test --workspaces
+```
+
+#### Filtering workspaces
+
+It's also possible to run a script in a single workspace using the `workspace`
+config along with a name or directory path:
+
+```
+npm test --workspace=a
+```
+
+The `workspace` config can also be specified multiple times in order to run a
+specific script in the context of multiple workspaces. When defining values for
+the `workspace` config in the command line, it also possible to use `-w` as a
+shorthand, e.g:
+
+```
+npm test -w a -w b
+```
+
+This last command will run `test` in both `./packages/a` and `./packages/b`
+packages.

+### Running commands in the context of workspaces
+
+You man use the `workspace` configuration option to run commands in the context
+of a configured workspace.
+
+Following is a quick example on how to use the `npm run` command in the context
+of nested workspaces. For a project containing multiple workspaces, e.g:
+
+```
+.
++-- package.json
+`-- packages
+   +-- a
+   |   `-- package.json
+   `-- b
+       `-- package.json
+```
+
+By running a command using the `workspace` option, it's possible to run the
+given command in the context of that specific workspace. e.g:
+
+```
+npm run test --workspace=a
+```
+
+This will run the `test` script defined within the
+`./packages/a/package.json` file.
+
+Please note that you can also specify this argument multiple times in the
+command-line in order to target multiple workspaces, e.g:
+
+```
+npm run test --workspace=a --workspace=b
+```
+
+It's also possible to use the `workspaces` (plural) configuration option to
+enable the same behavior but running that command in the context of **all**
+configured workspaces. e.g:
+
+```
+npm run test --workspaces
+```
+
+Will run the `test` script in both `./packages/a` and `./packages/b`.
