[tschneidereit]

The TSC has discussed this and agree that the contributions are worthy of recognition in the Bytecode Alliance.

@beetrees, to finalize the addition, please send an email to tsc[@]bytecodealliance.org to let us know which address to use for communicating with you as a Recognized Contributor, and to confirm that you accept the nomination.

That address will be added to our RCs mailing list, which receives community and project updates every few weeks or so.

Once we've received that email, we'll add you to the mailing list and merge this PR.

Thank you!

Email confirming acceptance of the nomination has been received, and our RC mailing list updated accordingly. Thanks, @beetrees, and welcome!
