Add Accessibility Block plugin (blocks/accessibility) 1.0.1.0 for OJS 3.5

[edersotto]

Adds a new entry for the Accessibility Block plugin, a sidebar block that gives readers accessibility controls: zoom in (A+), zoom out (A-), a high-contrast toggle and a reset button. The reader preferences are stored in the browser and re-applied on every page of the journal.

• Repository: https://github.com/OJSBR/accessibility
• Release: 1.0.1.0 (branch stable-3_5_0)
• Package: https://github.com/OJSBR/accessibility/releases/download/1.0.1.0/accessibility-1.0.1.0.tar.gz
• Compatibility: OJS ~3.5.0.0
• Licence: GPL-3.0

Notes

• The package is a single accessibility/ directory with LICENSE at its root, and contains no composer/npm dependency files.
• Validated locally with xmllint --schema ./plugins.xsd ./plugins.xml --noout; the package URL resolves and its MD5 matches the entry.
• Ships in 6 languages (en, pt_BR, es, fr_FR, it, de) and includes a Cypress functional test (cypress/tests/functional/AccessibilityBlock.cy.js) written along the lines of the tests shipped with the OJS plugins.
• Accessibility details: real button elements with aria-label / aria-pressed, a visually hidden live region announcing the zoom level, and 40px minimum touch targets. The buttons reuse the active theme button style, with a zero-specificity fallback for themes that do not define it.
• The plugin modifies no core files and adds no database schema; disabling it removes the block entirely.
• I did not include a certification element, since that seems to be for the maintainers to decide.
