Test with injected external providers (#5652)

* fix: sending tx with injected provider (#5651)

Co-authored-by: Marin Petrunic <[email protected]>

* adding a test for using `ganache` provider

* enable the jsonrpc `id` to optionally be incremented starting from a number
 (Inspired by: #5373 (comment) and needed as a work around for blockchainsllc/in3#46)

* test with `in3` as a provider & skip `in3` test if it takes too long

* increase integration test timeout at web3 package

* add a test for using `hardhat` provider

* improve how legacy providers, such as hardhat, is used

* implement `isPromise` that works in the browsers

* refactor external providers tests

* update CHANGELOG.md
