[Feature]: `generatePath` should extract its required parameters from the URL

[macarie]

What is the new or updated feature that you are suggesting?

I think generatePath should extract its required parameters from the URL.

I found this "issue" when migrating from v5 to v6, thus removing @types/react-router-dom from the dev dependencies.

The generatePath signature from DefinitelyTyped (https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react-router/index.d.ts#L169) extracts the required parameters from the URL, while the official version (https://github.com/remix-run/react-router/blob/main/packages/react-router/lib/router.ts#L103 or https://github.com/remix-run/react-router/blob/dev/packages/router/utils.ts#L478?) does not.

IIRC, in v6, it should be easier to write the "extractor" as only required parameters and the * at the end are allowed.

Are there any reasons behind this divergence?

Why should this feature be included?

I've found that feature helpful, especially when building URLs from consts in different components/files.

This is already being looked at in #9090

Oh, nice! So happy that this is already being implemented 🙌🏼

I've only looked through issues and discussions, didn't think to look for a PR 😄
