Model card template: Move model usage instructions out of Bias section

[NimaBoscarino]

Not sure that ### How to Get Started with the Model belongs under the Bias, Risks, and Limitations section, so this PR changes it from a H3 to an H2.

cc-ing @EziOzoani @meg-huggingface for review on this PR

Has it been discussed on Slack btw? (if yes, I would refer to this discussion for more context, otherwise I'm fine with having only this PR)

[NimaBoscarino]

Nope, hasn't been discussed on Slack! I just ran into this while working on something and figured it was probably a mistake or a typo.

[Wauplin]

Yep agree with you, seems like a typo.
Approved the PR but please wait to get another approval from @EziOzoani or @meg-huggingface before merging, just to be sure :)
