Use conditional props for component in v-button

[azrikahar]

Description

After the dependency updates in #13713, <router-link>s are receiving the href prop even if it's undefined, which then causes the href it should have had (by using to) to be missing instead.

This uses v-bind to conditional pass href prop to prevent router-link from misbehaving.
