Is languages/gutenberg.pot generated by babel ?

[miya0001]

I haven't tried it with this project, but I saw it works as expected on my project with following command.

node_modules/@babel/cli/bin/babel.js ./src -x '.tsx' -x '.ts' --config-file ./.babelrc.i18n

.babelrc.i18n:

{
  "presets": ["@babel/preset-react", "@babel/preset-typescript"],
  "plugins": [["@wordpress/babel-plugin-makepot",{"output":"src/lang/lang.pot"}]]
}

It seems to me that the pot file should not be a commit.
