Forbid `$t` and friends in `data`

[allanlewis]

Please describe what the rule should do:

Use of $t and friends in components' data sections should be forbidden because it results in non-dynamic translations.

What category should the rule belong to?

• [ ] Enforces code style (layout)
• [x] Warns about a potential error (problem)
• [ ] Suggests an alternate way of doing something (suggestion)
• [ ] Other (please specify:)

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

data() {
  return {
    foo: this.$t('foo'),
  }
},
