[FIX] xml: escape chars in regex

There's an issue in odoo when extracing translatable source terms
from the bundled library file `o_spreadsheet.js`. Some terms are not
extracted.

Babel doesn't correctly tokenize the regex /"/
As a result, all following tokens are fucked up and source terms are no longer
exported after this point.

It seems to be known that babel js lexer isn't perfect.
