feat: Improve script injection and migrate to Manifest V3

[ChuHoMan]

resolve #17 #16

Hello, I have solved the problem of script injection displayed in the network (PS: partially based on the idea of react-devtools-extensions, the code has notes). During the process, I migrated to Manifest v3 because I could not use the browser.scripting property. However, Firefox does not support Manifest v3, so I built two dist dir.

Now it runs well, and I have tested it locally on Firefox and Chrome. Do you have any other suggestions?

When I enabled device mode with Chrome devtools, it will keep on showing Uncaught TypeError: t.extension.getURL is not a function, I think that is because User Agent is different when enabling device mode~

Yes, you are right, I also reproduced. But using browser.extension.getURL('injected.js') is the previous logic that has nothing to do with this PR. Maybe I can try to fix it later.
