fix: correct locale path in translation guide, add missing link attributes in footer, fix wasm version in readme

- footer.html: Instagram and LinkedIn links were missing target=_blank and rel=noopener noreferrer, unlike the other social links

- README.md: air-gapped manual steps referenced pymupdf-wasm@0.11.14 but the current default is 0.11.16
