fix: add specifier in package.json to expose all files in ./dist

[revosw]

Possibly fixes #700, #701 so that import "@glidejs/glide/css/glide.core.css" for example works again

Note that this is NOT TESTED. It seems legit that "./dist/*": "./dist/*" does expose all files in dist, but I have not personally tested that it works.

I have now tested it by:

1. Creating a brand new React vite project
2. pnpm install @glidejs/glide
3. Manually go to node_modules/@glidejs/glide/package.json and adding the "./dist/*": "./dist/*" specifier to exports
4. Doing pnpm run dev in the React project

I don't get any errors. When importing glide.core.css, the sources panel in devtools says that it is imported. When removing the import, it disappears from the sources panel. I think this is good

I don't seem to get any autocomplete for glide.esm.js, glide.js and glide.modular.esm.js. I do get all the autocomplete for the css files, however

This should allow people to build their projects again. In the meantime I will think how to reorganize this exports, thanks
