Fix grammar and formatting issues in README (#642)

- Fix typos: "Thease"→"These", "coppied"→"copied", "occured"→"occurred"
- Fix broken grammar in note and onResourceError description
- Add missing space in "Parameters-" labels
- Align mixed tab/space indentation in afterResponse example
- Use ESM import instead of require in generateFilename example (package is pure ESM)

-`.apply` method takes one argument - `registerAction` function which allows to add handlers for different actions. Action handlers are functions that are called by scraper on different stages of downloading website. For example `generateFilename` is called to generate filename for resource based on its url, `onResourceError` is called when error occured during requesting/handling/saving resource.

 You can add multiple plugins which register multiple actions. Plugins will be applied in order they were added to options.
 All actions should be regular or async functions. Scraper will call actions of specific type in order they were added and use result (if supported by action type) from last action call.
