Missing type definition for provider.logRetentionInDays

[frozenbonito]

provider.logRetentionInDays property requires number, but there is no type definition for it in config schema.
This issue breaks type coercion (#8319) and prevents making it configurable by option or environment variable.

serverless.yml

service: myservice

provider:
  name: aws
  region: us-east-1
  runtime: nodejs12.x
  logRetentionInDays: ${opt:log-retention}
