chore: prepare release (Chainlit#1595)

Bump version to 2.0rc0.

Bump changelog for 1.3.2 and 2.0rc0.

Build fixups (Chainlit#1462)

* (Ironically) ignore build script during package publication:
  - Avoids platform-specific wheels.
  - Ensures build script is not included in sdist.
* Remove legacy Node package build, now that poetry is leading.
* Run builds also for PR's to release branches.

The road to hell is paved with dirty workarounds.

Release prep for 1.3.1 (Chainlit#1483)

* Update server.py (Chainlit#1474)

Solving the underlying issue properly requires moving to HTTP only cookies, which is out of scope for now (we want to properly clean up auth). We're gonna ship this ASAP.

This reopens Chainlit#1101 and Chainlit#1438 .

* Changelog for 1.3.1 and 2.0.dev2.

* Bump version to 1.3.1.
