Replace v-html with v-safe-html in repository file table rows

What does this MR do and why?

From &4273 (closed)

Gitlab-org/gitlab lints against using v-html. It was implemented as per #232488 (closed) to prevent against XSS vulnerabilities and as part of the effort to improve frontend security posture.

The project has many v-html usages and we need to audit each one of them & replace with a secure alternative like v-safe-html or v-text wherever possible.

This MR replaces v-html with v-safe-html (by using GlSafeHTMLDirective) in app/assets/javascripts/repository/components/table/row.vue.
