docs: refresh JFrog Artifactory integration guide for SaaS (#28005)

## Summary

Refreshes the JFrog Artifactory integration guide to cover JFrog SaaS.
The JFrog-OAuth section previously implied the module was self-hosted
only and mixed the SaaS and self-hosted setup into one ambiguous step.

## Changes

- **JFrog-OAuth**: State the module works with both JFrog SaaS and
self-hosted (on-premises) Artifactory.
- **JFrog-OAuth**: Split setup into a SaaS UI flow (**External
Applications** > **Custom Integration**) and a self-hosted Helm
integration-template flow.
- **JFrog-OAuth**: Update the module example to
`registry.coder.com/coder/jfrog-oauth/coder`, `1.2.4`.
- **JFrog-Token**: Update the stale example to
`registry.coder.com/coder/jfrog-token/coder`, `1.2.2`.

## Validation

- `markdownlint-cli2` passes on the file.
- No emdash/endash.

 ### JFrog-OAuth
 
-This module is usable by JFrog self-hosted (on-premises) Artifactory as it
-requires configuring a custom integration. This integration benefits from Coder's [external-auth](../external-auth/index.md) feature allows each user to authenticate with Artifactory using an OAuth flow and issues user-scoped tokens to each user.
+This module works with both JFrog SaaS (for example, `example.jfrog.io`) and self-hosted (on-premises) Artifactory.
+It uses Coder's [external-auth](../external-auth/index.md) feature, so each user authenticates with Artifactory through an OAuth flow, and Coder issues a user-scoped access token to each workspace.
