Bump rollup from `2.x` to `4.x` in `@exile-watch/rollup-config`

[sbsrnt]

Important

There is a possibility @exile-watch/rollup-config may be replaced with a similar config in favor of https://rolldown.rs/.

Probably by the time all checkboxes are ticked, Rolldown may be production ready.
We may still hold on checking rolldown until there is a published minor version after the official first release.

User story
As a developer, I want to be fairly up to date with latest package versions and this applies to Rollup.

Current @exile-watch/rollup-config rollup version is sitting at 2.x, 2 major versions behind.

There are couple breaking changes, most notable that affect @exile-watch/rollup-config package directly:

• removal of acorn plugin [v4.0] Switch parser to SWC and introduce native/WASM code rollup/rollup#5073
  • That means acornInjectPlugins is no longer a valid option and needs to be removed from here
  • acorn-jsx dependency also needs to be removed
• From my brief testing there was a circular dependency issue with @rollup/plugin-commonjs so probably need to investigate this as well
• RollupWarning and WarningHandler have been removed [v4.0] Remove onwarn from normalized input options rollup/rollup#5147
  • I believe this is only a type change

Acceptance criteria

• acornInjectPlugins rollup config option is removed (need to see what's the impact)
• acorn-jsx dependency is uninstalled
• RollupWarning is replaced with RollupLog here and here
• Similarly to the bullet point above, WarningHandler is replaced with LoggingFunction
• Investigate if there are no circular dependency errors happening (there could be one coming from @rollup/plugin-commonjs
