Replace deprecated rollup-plugin-terser with @rollup/plugin-terser

New Pull Request

The rollup-plugin-terser has not had a commit in four years, has been deprecated, and is no longer maintained. Therefore, I have replaced it with its successor, @rollup/plugin-terser.

Additionally, I noticed that the makeMap function, which was passed to the pure_funcs option, is not defined anywhere in the codebase (as verified by a grep search). Including such a function that is undefined and potentially has side effects in the future is error-prone. Hence, I have removed this option.

Other PRs (such as apexcharts#3709) have updated dependencies without performing a build. Following this precedent, this PR does not include an updated build.
