fix: correct JSON escaping in Tuta additionalSettings

[pratham-jaiswal]

This fixes the additionalSettings JSON for the Tuta config (de.tutao.tutanota.json)

The previous value used invalid escaping for the regex in versionExtractionRegEx, which caused:

SyntaxError: Bad escaped character in JSON

This was breaking the build pipeline when buildData.js attempted to parse the generated config.

Root cause

The regex used \d directly inside a JSON string. Since additionalSettings itself is a stringified JSON object, the backslashes needed to be escaped twice.

Changes

• Corrected escaping for versionExtractionRegEx
• Ensured the config parses correctly through JSON.parse

Verification

Tested locally:

• node buildData.js now runs successfully
• Used the generated obtainium://app/... payload from “Add to Obtainium”
• Transferred to Android and imported successfully
• Correct app version is detected and displayed
• APK downloads and installs correctly
