Make UserID optional in GetUserProfile()

[itkq]

users.profile.get API takes user parameter as optional.
https://api.slack.com/methods/users.profile.get

This change breaks GetUserProfile interface.
The current interface does not allow the bot to retrieve
its own user profile.

Pull Request Guidelines

These are recommendations for pull requests.
They are strictly guidelines to help manage expectations.

PR preparation

Run make pr-prep from the root of the repository to run formatting, linting and tests.

Should this be an issue instead

• is it a convenience method? (no new functionality, streamlines some use case)
• exposes a previously private type, const, method, etc.
• is it application specific (caching, retry logic, rate limiting, etc)
• is it performance related.

API changes

Since API changes have to be maintained they undergo a more detailed review and are more likely to require changes.

• no tests, if you're adding to the API include at least a single test of the happy case.
• If you can accomplish your goal without changing the API, then do so.
• dependency changes. updates are okay. adding/removing need justification.

Examples of API changes that do not meet guidelines:

• in library cache for users. caches are use case specific.
• Convenience methods for Sending Messages, update, post, ephemeral, etc. consider opening an issue instead.

I found bots.info method which the bot can also retrieve its own user profile, but the current interface requires bot string as well...

Thank you!
As you mentioned, This changes break backward-compatibility.
So I plan to release this in the next minor version.

Slack API doc says the bot parameter optional, but when we tried this, it returned only ok...🤔

$ curl -H'Authorization: Bearer <bot_token>' https://slack.com/api/bots.info
{"ok":true}

Oh.. I got the same response, which means this method is not suitable for the use case above (I actually mentioned bots.info method without trying it out 🙄 ).
