fix: resolve dependency issues

[merceyz]

What's the problem this PR addresses?

• vue-template-compiler isn't declared as a dependency nor a peer dependency.
• Babel plugins aren't resolved before they are passed to Babel which makes it resolve them from the current working directory. This doesn't work in strict dependency environments and is prone to breaking if hoisting isn't in its favour.

How did you fix it?

• Declare vue-template-compiler as a peer dependency.
• require.resolve the plugins before passing them to Babel.
