Remove license comments from the UMD build

[sequba]

Context

• updated the webpack configuration to use the string-replace-loader plugin that removes all occurrences of the license comment from the UMD packages
• added a step that verifies the number of license comments in the build to the verify:umd script that is called in the GH workflow

It reduced the size of hyperformula.min.js by 1.90% (from 527K to 517K) and hyperformula.full.min.js by 1.45% (from 691K to 681K)
