fix: module export

[solaris007]

The current version 8.0.0 does not work in an ESM environment:

• type is not set to module in package.json
• src/index.js does not export module style (it can, now that Support extending ESM based configurations semantic-release/semantic-release#3037 is closed9

type is not set to module in package.json

I thought it wasn't needed but will try again

src/index.js does not export module style (it can, now that semantic-release/semantic-release#3037 is closed

I don't believe this is strictly required for ESM? It would require a breaking change since it requires a more current version of semantic-release than is currently defined in peer deps.

@pmowrer, not having a type property in the package.json will cause the following warning:

> npx --no-install -ws semantic-release -e semantic-release-monorepo

[9:41:46 AM] [semantic-release] › ℹ  Running semantic-release version 23.0.0
(node:2309) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)

I guess it can be technically ignored but should be curbed nonetheless.

Unfortunately semantic-release-monorepo breaks with semantic-release >= 20 for exactly the above reason. Here's the error:

The above is fixed by making index.js export ESM-style.

We'll have to find a way to support the latest versions of semantic-release.
