tex-babel{,-doc}: update to 3.53

* Extended \setlocalecaption to allow .template
* Allow access to some features in `ini` files even with `ldf`
  ones.
* Tool to create ldf files with a (more or less) GUI (only
  GitHub).
* Captions for Sinhala (thanks to Nisal D Bandara).
* Fixes:
  - Not really a fix, but I started working on `picture` with
    bidi in lua.
  - Parenthesis sometimes mirrored at the end of math with
    bidi=basic.
