rollup-plugin-terser reappeared in package.json

[dilyanpalauzov]

#693 has replaced in package.json "rollup-plugin-terser" with "@rollup/plugin-terser". Later on, #662 added to package.json again "rollup-plugin-terser". Why?

Ah I probably messed up the merge conflict while rebasing, apologies. I'll revert once I'm back at my laptop.
