Remove lang="html" in the template.

[serebrov]

After vue-cli 5 upgrade, we are getting an error in jest tests:

$ npm run test:unit -- tests/unit/test.spec.ts

Component /.../frontend/node_modules/vue-wait/src/components/v-wait.vue uses lang html for template, however it is not installed.

 FAIL  tests/unit/test.spec.ts
  ● Test suite failed to run

    [vue-jest] Error: Vue template compilation failed

Removing lang="html" in the component template fixes the issue.

@f could you approve and merge this? <3 We're using this in our company and breaks when migrating to Vitejs, this would solve it.
