tolerance, receivedAt, timestamp are now optional in Webhook.ts

[prathmesh-stripe]

Why?

In v22, several webhook method parameters that were previously optional in manually maintained became required due to a type consolidation.
generateTestHeaderString only truly requires payload and secret (all other fields have defaults). verifyHeader/constructEvent work without explicit tolerance and cryptoProvider arguments. Users upgrading to v22 now get TypeScript errors when calling these methods with the same arguments that worked in v21.

What?

• Made timestamp, scheme, signature, and cryptoProvider optional in WebhookTestHeaderOptions
• Made tolerance and cryptoProvider optional in verifyHeader/verifyHeaderAsync signatures
• Made scheme optional in parseHeader
• Updated prepareOptions return type to reflect that defaulted fields are resolved to non-optional
• Added tests covering all optional parameter default behaviors

Looks good, but I had a comment about the default.

It's how it's always worked so we're not making things worse, but we should ship with better defaults in the future.
