chore: update interpolation syntax for i18n files (#10198)

There were two warnings showing up on new teams page

1. `errorMessage` prop was getting invalid value, this was because were
short circuting the error message using `&&`, fixed it by using ternary
operator
2. `vue-i18n` has deprecated [rails
syntax](https://vue-i18n.intlify.dev/guide/essentials/syntax#rails-i18n-format),
fixed that warning by removing `%` before `{}` for interpolation

> Note: the `vue-i18n` deprecation needs to be handled, but we can do it
later
