Rule Proposal: template-no-target-blank

[sosukesuzuki]

Please describe what the rule should do:

This rule should warn when rel='noreferrer noopener' does not exist in attributes of an anchor tag with target="_blank".

What category should the rule belong to?

• Enforces code style
• Warns about a potential error
• Suggests an alternate way of doing something
• Other (please specify:)

Provide 2-3 code examples that this rule should warn about:

<template>
  <a href="http://example.com" target="_blank">link</a>
</template>

A rule does exist for this problem in eslint-plugin-react

To any maintainer. Can I work on this?

Thank you for this rule proposal.

I think it is good to add this rule to eslint-plugin-vue.
I'm not familiar with this vulnerability, so I'm not sure about the rule details.
