[Remove Vuetify from Studio] Remove temporary ::v-deep override from external links on licenses modal

[vtushar06]

Summary

Removes temporary ::v-deep CSS override for .license-link that was added in PR #5107 to fix KExternalLink's incorrect margin.

This override is no longer needed since the root cause has been fixed in KDS PR #1125 (merged) and Studio now has the latest KDS version.

Changes:

• Removed ::v-deep span { margin-left: 0 !important; } override from RequestForm.vue

Verification:

• Checked "Learn More" links in Settings > Storage > Request More Space form display correctly with proper spacing

Thank you @vtushar06 - all good.

I need to check with the team on the failing check before we merge. I don't think it's related to your changes.
