chore: patch mysql2 package for ensuring special characters in mysql password and username when only url is provided in config

[samarpanB]

With mysql latest versions, its mandatory to have special characters in password as per security policy in mysql. But with password having '@' or some other special characters, the encoded url string is not decoded properly. This issue has been discussed in detail here too - sidorares/node-mysql2#1621

Referring to the above PR discussion and its related issues discussion, I have added a patch for the library. I am raising a PR on mysql2 library too. Until my PR is merged, this patch can work and ensure test cases pass.

PR added to mysql2 library - sidorares/node-mysql2#2277

Our CI checks are also failing due to this.
