feat(prefer-template): ignore style block

fix #2712

Looks good to me. But I'm curious why the erroneous behavior was actually covered by a test case 🤔
Was it intentional?

Ah, I found that the original test case behavior is correct though.
The v-bind in CSS must be wrapped in quotes. So the user's issue should be resolved by changing width: v-bind(someWidth + 'px'); to width: v-bind("someWidth + 'px'");.
Then, the autofix will correct it to v-bind("`${someWidth}px`"), which should then be right.

I'm going to close this PR for now and will further elaborate in the issue discussion.
