Exclude nested dir from top config

[tanguyantoine]

Firstly, release-please is incredibly useful. Thank you

Is your feature request related to a problem? Please describe.
I'm working on a monorepo and have many packages.
The monorepo also holds some configuration that needs to be excluded in my case (deploy folder)
These deploy folders exist under each packages:

• packages/one/deploy
• packages/two/deploy

Describe the solution you'd like
I would like to be able to use exclude-paths as is

{
  "exclude-paths": ["**/deploy"]
}

Describe alternatives you've considered
As of today, the alternative is to specify the exclude-paths under each package configuration
