merge release notes

[dherman]

Merge stuff from cli/RELEASES.md into RELEASES.md -- since the PRs reference the neon-cli repo either change the links to reference that repo or link to the commits.

Hi @dherman! I'd like to tackle this bug if it's still unassigned. Would I be combining all of the content from cli/RELEASES.md into RELEASES.md?

[dherman]

@seanprashad Yes, exactly :D When you bring the cli/RELEASES.md comments into RELEASES.md, wherever they reference neon issues/PRs, you can eliminate the explicit reference to neon (e.g., "#214" can just become "#214"), and wherever they reference neon-cli issues/PRs, please make those explicitly reference the old repo (e.g., "TypeScript upgrade fixes (#62, #65)" becomes "TypeScript upgrade fixes (neon-bindings/neon-cli#62, neon-bindings/neon-cli#65)").

Also, would you mind fixing up the markdown so they render as actual links?

[seanprashad]

Got it! I will take a look at merging the two files and fixing up the markdown to render links and get back to you if I have any questions!
