bug(init): provider names with a dot are not saved correctlty

[dwmkerr]

Using the name openai-3.5 gives:

providers:
  openai-3:
    '5':
      name: openai-3.5
      type: openai
      baseURL: https://api.openai.com/v1/
      model: gpt-3.5-turbo
      apiKey: '123'
provider: openai-3.5

This is likely an error in the 'enrichProperty' code
