fix: Remove .ts suffix from NVD3 imports

[villebro]

🐛 Bug Fix

The current released version of NVD3 viz' doesn't work due to the import referencing the ts files (the linter forced me to add the suffix). I'm not really sure we should have that check here, as it appears to be causing broken releases.
