[Feature] Verbose flag for installation

[cawolfdev]

• I'd be willing to implement this feature (contributing guide)
• This feature is important to have in this repository; a contrib plugin wouldn't do

Describe the user story

As a developer, I would like to know why yarn install fails.

NPM: repository installs without error, on all environments
Yarn 1: repository installs without error, on all environments.
Yarn 3.5: Local machine, repository installs without error
Yarn 3.5: Different machine, repository installs without error
Yarn 3.5: Jenkins server: repository fails to install.

There is no way to debug what is failing or why.

It would be useful to know what yarn is attemping to do when it errors, or locks up.

Logs printed to the console:

[Pipeline] }

Yarn 3.5 simply stops for 27 minutes. Doing, as far as I can tell -- absolutely nothing.

Describe the solution you'd like

To have clear information about what yarn install is doing, so that when it fails on CI, it can be diagnosed. To have similar debugging issues as yarn 1, or npm for when yarn install fails to install anything.

Implement a new config option --verbose, or respect a flag such as YARN_LOG_LEVEL to control verbosity.

Describe the drawbacks of your solution

None.

Describe alternatives you've considered

No documentation as to how to hook into the installation process in order to output logs.
