Pyscript 1.5.0 release

The 1.5.0 release supports the HASS 2023.7 and 2023.8 beta releases, and should be backward compatible with older versions.

This release has several updates and bug fixes:

• Service calls no longer support the optional limit keyword timeout argument (when blocking=True), since it was removed in HASS 2023.7.
• Added translations/de.json language file (see #462 from @anwirs).
• Boolean or now returns False not 0 when subexpressions are False (see issue #469 from @redlefloh).
• Directly access hass.data[DATA_RESTORE_STATE] to avoid deprecated api; this is a hack and I need a better fix (see #473 from @slomanl1).
• Added support for service responses (see #495 from @matzman666).
• Fix import of HASS Event following change to 2023.8 beta (see #500 from @rccoleman).
• Log warning if user calls time.sleep(), which blocks, and call asyncio.sleep() instead.
• Bump the required version of the watchdog module to 2.3.1, which matches the required version in the folder_watcher integration in 2023.7.
• Bump Python to version to 3.11 for tests, and updated various versions of packages.

Thanks to everyone who contributed PRs and reported issues.

Enjoy!
