Release 10.1.5

Found another bug while trying to make the release.

Running `npm run nodeps` last breaks dynamic importing of the DayJS
translations. I'm not sure why, I think maybe because of broken `.map`
files.

The fix for now is to move the js-po files out of the way, and then copy
them back in after running `npm run build`.

Hopefully all of this won't be necessary with gettext 0.22 which should
support template literals
