core-js-pure - npm Package Versions

Added some fixes and workarounds of FF30- typed arrays bug that does not properly convert objects to numbers
Added sideEffects field to core-js-pure package.json for better tree shaking, #1117
Dropped semver dependency from core-js-compat
- semver package (ironically) added a breaking change and dropped NodeJS 8 support in the minor 7.1 version, after that semver in core-js-compat was pinned to 7.0 since for avoiding breaking changes it should support NodeJS 8. However, since core-js-compat is usually used with other packages that use semver dependency, it causes multiple duplication of semver in dependencies. So I decided to remove semver dependency and replace it with a couple of simple helpers.
Added Bun 0.1.6-0.1.11 compat data
Added Deno 1.25 compat data mapping
Updated Electron 21 compat data mapping
Some stylistic changes, minor fixes, and improvements

3.25.0 - 2022.08.25

Added Object.prototype.__proto__ polyfill
- It's optional, legacy, and in some cases (mainly because of developers' mistakes) can cause problems, but some libraries depend on it, and most code can't work without the proper libraries' ecosystem
- Only for modern engines where this feature is missed (like Deno), it's not installed in IE10- since here we have no proper way setting of the prototype
- Without fixes of early implementations where it's not an accessor since those fixes are impossible
- Only for the global version
Considering document.all as an object in some missed cases, see ECMAScript Annex B 3.6
Avoiding unnecessary promise creation and validation result in %WrapForValid(Async)IteratorPrototype%.return, proposal-iterator-helpers/215
Fixed omitting the result of proxing .return in %IteratorHelperPrototype%.return, #1116
Fixed the order creation of properties of iteration result object of some iterators (value should be created before done)
Fixed some cases of Safari < 13 bug - silent on non-writable array .length setting
Fixed ArrayBuffer.length in V8 ~ Chrome 27-
Relaxed condition of re-usage native WeakMap for internal states with multiple core-js copies
Availability cloning of FileList in the structuredClone polyfill extended to some more old engines versions
Some stylistic changes and minor fixes
Throwing a TypeError in core-js-compat / core-js-builder in case of passing invalid module names / filters for avoiding unexpected result, related to #1115
Added missed NodeJS 13.2 to esmodules core-js-compat / core-js-builder target
Added Electron 21 compat data mapping
Added Oculus Browser 23.0 compat data mapping
