fix: list Slack as an auth provider for the authorization URL

[tgwizard]

Description

Slack wasn't in here, but it works. I want to use it in workos_client.user_management.get_authorization_url. (This list seems somewhat inconsistent with other lists).

Documentation

Does this require changes to the WorkOS Docs? E.g. the API Reference or code snippets need updates.

[x] No

If yes, link a related docs PR and add a docs maintainer as a reviewer. Their approval is required.

Greptile Summary

This PR expands the SSOProvider and UserManagementAuthenticationProvider enums (and their corresponding Literal TypeAliases) to include Slack and eight other OAuth providers that were previously missing. Both the Enum members and the Literal TypeAliases are kept in sync across both files, and the previously-flagged P1 (missing "SlackOAuth" in UserManagementAuthenticationProviderLiteral) is fully resolved in this revision.

Confidence Score: 5/5

Safe to merge — no P0/P1 issues; only a P2 note about manual edits to auto-generated files.

All Enum/Literal pairs are in sync, the previous P1 is resolved, and no logic or security concerns are introduced. The sole open concern (auto-generated file header) is P2.

No files require special attention beyond the auto-generated file caveat already noted.

Important Files Changed

Filename	Overview
src/workos/sso/models/sso_provider.py	Added 9 new OAuth providers (Bitbucket, Discord, GitLab, Intuit, LinkedIn, Salesforce, Slack, Vercel, VercelMarketplace, Xero) to both the Enum and Literal TypeAlias, keeping them in sync. File header says auto-generated.
src/workos/user_management/models/user_management_authentication_provider.py	Added same 9 new OAuth providers to both the Enum and Literal TypeAlias (including SlackOAuth), fully resolving the previously-flagged P1. Also consolidated duplicate typing imports. File header says auto-generated.

Hey, thanks for this!

These files are now automatically generated by our OpenAPI spec and completely machine generated (This file is auto-generated by oagen.) -- so I updated that YAML and produced the full complete list here. This'll be out in the next patch.
