fix(slack): don't raise RuntimeError if unable to fetch property in slack request

[cathteng]

Resolves #67679

We are currently raising a RuntimeError if the channel_id, team_id, or user_id does not exist in an incoming Slack request. We use team_id and user_id here:

sentry/src/sentry/integrations/slack/requests/base.py

Lines 82 to 92 in 121726d

	try:
	team_id = self.team_id
	user_id = self.user_id
	except Exception:
	pass
	context = integration_service.get_integration_identity_context(
	integration_provider="slack",
	integration_external_id=team_id,
	identity_external_id=user_id,
	identity_provider_external_id=team_id,
	)

And these values can be None, so we don't need to be raising a RuntimeError:

sentry/src/sentry/services/hybrid_cloud/integration/impl.py

Lines 457 to 464 in 121726d

	def get_integration_identity_context(
	self,
	*,
	integration_provider: str | None = None,
	integration_external_id: str | None = None,
	identity_external_id: str | None = None,
	identity_provider_external_id: str | None = None,
	) -> RpcIntegrationIdentityContext:

NOTE: Not yet sure if it's okay for channel_id to be None. We can remove that part if need be.

Replacing get_field_id which raises the error with _get_field_id_option which can return None should fix this.

Let's make sure this doesn't break our async process where we try to get the team/channel id when the user only passes in team/channel name

[ykamo001]

could we use _get_field_id_option here as well, or no? Wonder why it's different

[cathteng]

we always expect a channel. i forgot to undo the type change
