Method files.upload is no longer supported by Slack for new Applications

[george-viaud]

It seems that as of the 16th of May, 2024 the files.upload method is no longer authorized for new bots.

The current client api definitions don't appear to have a filesGetUploadURLExternal() or filesCompleteUploadExternal() method (or I'm calling them incorrectly)

According to Slack, support for files.Upload ends March 11, 2025.

Per @george-viaud question, should filesGetUploadURLExternal() and filesCompleteUploadExternal() appear in the SDK?

Would someone be able to submit a pull request about this?

Some documentation:

@damienalexandre When I regenerated the client it converted the entire normalizer directory (448 files) to formal ::class from strings. Are you okay with me including that in the PR?

On a side note,
It looks like Slack is no longer updating the spec that is hosted on Slack's github used in UpdateSpecificationCommand.php. Given this, will all updates have be hand coded going forward in the patched schema?

#176

Based on slacks new file upload flow

1. Get upload url from call to files.getUploadURLExternal
2. Send post request to returned url
3. finalize upload with call to files.completeUploadExternal

Should we add an additional post method to the spec to facilitate the sending in step 2 @damienalexandre ?

For information in their official Slack node sdk, they implemented a dedicated filesUploadV2 method that seems to follow this new flow, so I think it could be a good idea to also implement one.
