Upgrade Pydantic to v2

[jake-skipper]

Runway uses Pydantic extensively, and awhile back they moved to v2. We haven't received those updates due to package pinning and some changes will be required to move to v2.

The decision was made to perform this upgrade, even though it is mildly breaking, in a minor release rather than major.

Tasks to be completed:

• EoL of binary releases (pyinstaller) to S3 and npm (end support for installing via cURL & npm #2508)
  • remove jobs that build, publish, etc these
• remove code and dependencies specific to pyinstaller (end support for installing via cURL & npm #2508)
• mark npm package as deprecated with message
• update install docs & README (end support for installing via cURL & npm #2508)
• update pyright to the latest version now that it can be updated (upgrade to pydantic ^2 #2518)
