chore(credential-provider-imds): providerConfigFromInit arrow function

[trivikr]

Issue #, if available:
N/A

Description of changes:
converts providerConfigFromInit to an arrow function, and add a comment about DEFAULT_MAX_RETRIES

• DEFAULT_MAX_RETRIES is 0, as it's the default in AWS SDK for Python and CLI (code)
• AWS SDK for JavaScript v2 has two attempts though (code)
