Outdated documentation for "Hinted Sign In"

[mrtmm]

The documentation suggests that there is a possibility to construct "hinted links" that will allow a user to log in via a Third Party and land on course pages. However, this feature appears to have been broken for quite a while as discussed in the following forum topics:

• https://discuss.openedx.org/t/whats-the-deal-with-tpa-hinted-links-in-nutmeg-olive/8436
• https://discuss.openedx.org/t/tpa-hinted-links-with-the-learning-mfe/12427

At the moment the documentation still gives examples to the legacy LMS and does not mention if this feature will be or was never meant to work with the Learning MFE.
