feat: add Unicode quotation mark input rule for quote blocks

[YousefED]

Summary

Add an input rule that converts Unicode quotation mark characters (e.g. ", ", «, », „) followed by a space into a quote block, complementing the existing > shortcut.

Ref: suitenumerique/docs#1955 (comment)

Rationale

Many keyboard layouts (especially non-US ones) produce Unicode quotation marks by default rather than the ASCII > character. Users intuitively type a quotation mark followed by a space to start a quote, and this change makes that work by matching any character in the Unicode Quotation_Mark category via \p{Quotation_Mark}.

Changes

• Added a new input rule in packages/core/src/blocks/Quote/block.ts using the regex ^\p{Quotation_Mark}\s$ (with the u flag) to trigger quote block conversion.

Impact

No impact on existing functionality — the existing > input rule is unchanged. This is purely additive.

Testing

• Manual testing with various Unicode quotation characters.

Checklist

• Code follows the project's coding standards.
• Unit tests covering the new feature have been added.
• All existing tests pass.
• The documentation has been updated to reflect the new feature

Additional Notes

The \p{Quotation_Mark} Unicode property covers all quotation mark characters defined by Unicode, including but not limited to: ", ", ", ', ', «, », „, ‟, ‹, ›.

Release Notes

• New Features
  • Added keyboard shortcut support for creating quote blocks using Unicode quotation marks. Users can now type a quotation mark followed by a space to create a quote block, providing an alternative to the existing > shortcut.

📝 Walkthrough

Walkthrough

The Quote block's input rules configuration gains an additional pattern-matching rule. The new rule detects when users type a Unicode quotation mark character at the start of input followed by a space, automatically converting it to a quote block—mirroring the existing > shortcut behavior.

🐰 A quote mark whispers soft and true,
Press space and see what magic grew—
A block appears, both quick and neat,
Making markdown input sweet! ✨

87-95: Add a regression test for the Unicode quote input rule.

The implementation matches the existing input-rule pattern, but this new Unicode shortcut should have at least one focused test covering a representative character like « or “ to prevent future regressions.

regression test that exercises the Unicode quote input rule in the Quote block:
write a unit test that simulates typing a representative Unicode quote character
plus a space (e.g. "« " and/or "“ ") and asserts the input-rule (the object with
find: new RegExp(`^\\p{Quotation_Mark}\\s$`, "u") in the Quote block) produces a
node of type "quote" with the expected props; place the test alongside the other
block input-rule tests, use the same editor/test helpers (applyInputRule or the
project’s test editor harness), and include an explicit assertion so future
changes to the regex or rule behavior will fail the test if broken.
