Pyscript 1.4.0 release

The 1.4.0 release supports the HASS 2023.3 release.

This release has several bug fixes:

• Boolean operators (eg: and) return correct type, not integer (see #335); reported by @ccapndave.
• Fixed setting of kwargs when state_hold != None (see #374, #382); reported by @jkrasinger and PR by @ALERTua.
• Decorator function arguments now expand *list (see #420); reported by @fovea1959.
• Jupyter kernel interface ignores comm_open, comm_msg and comm_close messages (see #390); reported by @tms320.
• Fix boolean operator truth test (see #438); reported by @Kaptensanders.
• Fixed unexpected triggers by @event_trigger due to prior trigger variables persisting in the context's symbol table; fixed by ensuring local symbol table is overwritten by default (see #439); reported by @Michael-CGN.
• Ensure user decorator functions start triggers in correct context (see #428, #457); reported by @j-steve.
• Added translations/sk.json (see #441); PR by @misa1515.
• Added functools to ALLOWED_IMPORTS (see #432); requested by @oxan.
• Bump Python to version to 3.10 for tests, and updated various versions of packages.
• Bump the required version of the watchdog module to 2.2.1, which matches the required version in the folder_watcher integration in 2023.6.
• Update README.md to correct HACS URL (see #348); PR by @wrt54g).
• Fix link to developer docs (see #373); PR by @robertgresock.

Enjoy!
