chore: migrate from lit-html to vue

[The-x-35]

Closes #300

I replaced the code popup-script.ts to call an App.vue file with the vue code and reimplemented all the functionalities and designs exactly in App.vue. I have tested it and it works same as before.

Look into the comments

there are discussions happening on the node level to remove some ambiguity with defining package managers like this.

we can revisit this once we've more clarity on the matter on industry level. for now we can remove it.

Sir I have not added this line, it was added implicitly by the corepack and when I try to remove it and try to build the project again, it gets added back automatically by the corepack. You can see in the below screenshot

I checked the docs and could not find a way to remove it, so keeping this in the next commit in this PR.

Just the package manager issue, I am unable to solve, please check the comments on that when to see the issue.
