Use eslint typescript parser

[dschmidt]

This does basically the same (and for the obvious same reasons) as #107

It additionally updates the lock file and adds support for line numbers in .ts files (and typescript in .vue files). Also it does not enable the range option of typescript-estree, which I didn't seem to need. I'm happy to hear why it was used in #107

@vperron Is there any chance this will be merged?

FWIW I/we currently still maintain a fork here: https://github.com/owncloud/easygettext

In https://github.com/owncloud/web we just reference it like this:

    "easygettext": "https://github.com/owncloud/easygettext/archive/refs/tags/v2.18.2-oc.tar.gz",

It has this PR and a few minor fixes regarding vue templates included.

Meanwhile https://github.com/owncloud/web has switched to vue3-gettext which uses gettext-extractor internally.
