feat: Add zio-http multipart body support

[seakayone]

Resolves #2518

Currently tests fail because the incoming ServerRequest contains the multiple parts, but when calling zio.http.Request.body.[asMultipartFormStream|asMultiPartForm] they only ever return the single, first part.

Seems to be a bug in zio-http: zio/zio-http#2411

Bug was fixed and released. I have let the build run in my own actions and it succeded: https://github.com/seakayone/tapir/actions/runs/9943391610

@seakayone now that #3690 is merged, can you put up this PR for review?

[seakayone]

I am planning to finalize this PR in the next couple of days hopefully.

There's some problems updating ZIO, I think we'll need to first tackle #3876, and then get back to this PR. Sorry for the problems :)

Found the problem in zio-http: zio/zio-http#2977

Hello.
Any news on this one and #3876 ?
Really eager to start using multipart requests -_-

@seakayone zio/zio-http#2977 was closed

@adamw Is there anything blocking for this to be merged? The underlying bugs are resolved and we are waiting for this fix. Thanks!

I'm guessing it's the same reason

[adamw]

@resilica @geeeezmo yes, unfortunately RC9 had a bug which prevented the update, there's another one now in RC10.

[alexander-klimov]

@seakayone can this PR be made public so it can be reviewed?
Because #4034 that updates zio-http to 3.0.0 has been merged.

[adamw]

Thanks for the work, needed a little push to get over the finish line, tests are now green :)

[alexander-klimov]

Thank you, Adam, for all the work you do.
Can't wait for the next release 🙃

[seakayone]

@adamw Thanks for finalizing this.
