Update Credits for GHE

[kathy-phet]

I was reviewing the credits for GHE, and have some suggested additions. I'm checking with our Mark for input though. Current from phettest:

Within Sim Credits:

Additions to "Team": Mark Nielsen (all a11y aspects)

Addition to "Thanks": HHMI BioInteractive Team for their partnership on the inclusive design and accessibility of this simulation. This simulation is dedicated to the memory of Ron LeMaster.

On the website: Add Mark Nielsen to team Add Thanks To section with above.

Good catch @kathy-phet! These changes all look good to me. Would you like to confirm the "Thanks" language with HHMI before we make the commits?

In an email response to @kathy-phet's questions, Mark said:

Thanks for the heads up. Feel free to add me to the credits (I didn’t get a screenshot).

I think you could just strike the word “team” from the Thanks section:

Thanks: HHMI BioInteractive for their partnership on the inclusive design and accessibility of this simulation.

Best,

Mark

Thanks @jbphet looks good on main & 1.3, closing.

Let's keep this open until the website is also updated with Mark and HHMI. Thanks!
