[Website] Add Blog about Comet Donation

[alamb]

Closes https://github.com/apache/arrow-datafusion-comet/issues/6

Rationale: We should tell the world about the Comet donation.

See background and more details on the mailing list: https://lists.apache.org/thread/0q1rb11jtpopc7vt1ffdzro0omblsh0s

@sunchao / @viirya do you know of any benchmark results that we can share about comet (e.g. "it ran the same query 30% faster with 50% the resources")? I realize we may not have numbers that can be shared at this time, but if we did I think it would make this post more compelling

[sunchao]

@alamb we don't have numbers with Comet yet, but we are working on this and hopefully it will be available in the 1-2 months.

I'm hoping we can have another blog post right after the initial release, with some benchmark numbers.

That makes a lot of sense. I put a note about working on an initial release and another update after that in b3d17ce

I plan to publish this blog tomorrow, March 5, unless anyone would like more time to review or has other thoughts. Thank you all for the feedback so far

[alamb]

Sorry I forgot to hit the button yesterday. I guess it will be published today March 6

Thanks everyone for the help
