Upgrade to 1.0.27

Concerns: pushword/admin-block-editor, pushword/core, pushword/flat

Paragraph attributes on the same line

Paragraphs beginning with {.class} Text now apply the class and render inline Markdown. No action is needed.

Typographic quotes inside Twig tags

The flat export and the editor no longer straighten quotes inside {{ }} and {% %}. An earlier export could turn 'l’été' into 'l'été', which breaks the Twig block: the page renders without it.

Sites with flat content that ran an export since rc865. Run pw:page-scan --skip-external and restore the ’ in the Twig tags of every page it flags twig-error.
