Switch every code example to use language selected in Get Started docs.

It's a bit cumbersome to go through and select TS for each individual code example, or to switch them back to JS and do the same.

Would be nice to select the language once and have all examples switch to it.

@bluebill1049 I'm down to handle this if it seems useful.

That would be great! thanks in advance. So just switch code once and apply all would be great.

@micphi any news on this?
