Repo link is hardcoded to "GitHub"

[inosik]

We host our own GitLab instance and I configured VuePress like this:

module.exports = {
  themeConfig: {
    repo: 'https://gitlab.my-company.local/my-team/our-product'
  }
}

The link to the repository still says "GitHub", because it's hardcoded in NavLinks.vue.
