Describe the bug

The error messages:

• "{directive}" is an unknown directive for pyright comment; expected "strict" or "basic" (pyrightCommentUnknownDirective)
• Pyright comment must be followed by a directive (basic or strict) or a diagnostic rule (pyrightCommentMissingDirective)

are not updated. It still only includes basic and strict even when standard mode is already supported since 1.1.339 and the false positive of the message is also fixed in 1.1.383.

Code sample in pyright playground

# Here shows pyright file-level type checking mode directives.
# 'none' and 'all' are just for comparison, they are indeed not supported.

# pyright: none
# pyright: basic
# pyright: standard
# pyright: strict
# pyright: all

# pyright:

VS Code extension or command-line

Reproducible in Pylance v2025.8.3 and Pyright 1.1.383 (the version that standard begins not to report error) and latest over pyright-play.net.
