chore(web|react): update build target from ES2020 to ES2015

[theashraf]

Changes:

• Build dotlottie-web and dotlottie-react for ES2015 instead of ES2020.
• This resolves issues on platforms that don't support ES2020 by default, ensuring compatibility with ES6.
• Added a babel example to illustrate cases where ES2020 features, such as optional chaining, are not supported.
