File extensions changed—now they align with thee,

Pull request overview

This PR updates the preact build script to align with a breaking change in v16 where the output file extensions for CommonJS and ES modules were changed. The build system now generates .cjs and .mjs extensions instead of .js for these module formats, resulting in filenames like *.cjs.cjs and *.esm.mjs.

Changes:

• Updated glob patterns in the preact build script to match the new file extensions (.cjs.cjs for CommonJS and .esm.mjs for ES modules)

Thanks @silviuaavram !

[silviuaavram]

@kentcdodds I feel this is actually a fix to the v16 breaking change. Do you have any project that uses preact?

[kentcdodds]

You're right, probably didn't need to make it a breaking change. But meh. 😅

I'm fixing the release script right now. A new release should be published soon.
