@ionic/utils-subprocess 2.1.12 change log does not mention node 16 is now the minimum version

**Description:**
I'm currently upgrading to Capacitor 3 (yes, I'm behind, I've having to upgrade due to jcenter going down) and I'm also stuck on node 12. Trying to run `npx cap sync ios` gives me:

```
promise.p.stdout?.pipe(stdoutBuf);
^

SyntaxError: Unexpected token '.'
```

Because 12 does not have option chaining. I scanned the change log and found that in 2.0.0 the minimum was increased to node 10 but no other mention. Then scanning through the code I found [this commit](https://github.com/ionic-team/ionic-cli/commit/85fb4fac177721cfcfb32b3eebe0c430d380de0e) which says the minimum is being bumped to node 16. This does not seem appropriate for a patch version (2.1.11 -> 2.1.12)

**Steps to Reproduce:**

Try to use capacitor cli v3 with node 12

**Output:**

See above.

**My `ionic info`:**

```
N/A
```

**Other Information:**

This fix will probably be to try and pin @ionic/utils-subprocess at 2.1.11 but I wanted to record this for others running into the same issue (possibly for the same reasons, having to upgrade due to jcenter/jfrog).

Review the @ionic/utils-subprocess 2.1.12 changelog and the linked commit that raised the minimum Node version. Update the changelog to state that Node 16 is required for this release, then verify that the version and wording accurately describe the compatibility change.
