gulp-shell has one deprecated dependency and 2 high severity vulnerabilities

[bartread]

I'm resurrecting an old project of mine and am installing up to date versions of all dependencies. When I got to gulp-shell I noticed the following:

% npm install gulp-shell --save-dev
npm warn deprecated lodash.template@4.5.0: This package is deprecated. Use https://socket.dev/npm/package/eta instead.

added 6 packages, and audited 378 packages in 762ms

38 packages are looking for funding
  run `npm fund` for details

2 high severity vulnerabilities

This package is only used as part of my build, so perhaps not an immediate concern, but I think it's worth updating all dependencies. I see there are a number of unmerged PRs raised by dependabot that would probably fix the above, so would probably be worth merging.
