fix(scripts): apply Liferay-specific Prettier overrides to TS also

Noticed while testing a PR for:

#92

that we aren't applying our Liferay-specific Prettier overrides to TS
files. ie. we're not enforcing this:

    }
    else {

Test plan:

Add a ".ts" file, "x.ts" with these contents:

    if (true) {
    alert('t');
    } else {
        alert('f');
    }

Add an "npmscripts.config.js" file (you don't need the ".md" and ".yml"
in there, but this is the file I had to create to test the other PR
anyway, so I'm just using the same one):

    module.exports = {
            check: ['**/*.{md,ts,yml}'],
            fix: ['**/*.{md,ts,yml}'],
    }

Run `projects/npm-tools/packages/npm-scripts/bin/liferay-npm-scripts.js
check` and see the error reported.

Run `projects/npm-tools/packages/npm-scripts/bin/liferay-npm-scripts.js
fix` and see the code fixed to:

    if (true) {
            alert('t');
    }
    else {
            alert('f');
    }
