Upgrade commitlint and its dependencies

Upgrade commitlint and its dependencies to the latest
version.

I installed node 14 using curl because node version in
apt is 12 and with this version I get this error in jest
installation:
```
error @jest/[email protected]: The engine "node" is incompatible with this module. Expected version "^14.15.0 || ^16.10.0 || >=18.0.0". Got "12.22.9"
```
