feat(Plugin): CopyFileContents

[Obsidianninja11]

Adds a button to copy the contents of a text file (even if the text isn't in the tiny preview).
After clicking, the copy icon will turn into a checkmark (like in large codeblocks), and the text will be copied to your clipboard.
For files over 50kb (50 thousand characters) that don't fully show in the "View whole file" preview, it shows "File too large to copy". I made a version that fetches files that are large, but I don't think that's necessary for 99% of users, and it could lead to problems if a user tries to copy a huge file.
This pr also updates the copy icon in components\icons.tsx (because the icon is used in this plugin), as the icon that was in there is long outdated.

A file containing 51kb that is unable to be copied (the first 683 numbers in the fibonacci sequence in this example).

You never change setRecentlyCopied back to false, is that intended?

Yes. That's how it works in code blocks, so I recreated it here.

I still feel like it should

I added a toast when copying. It's currently stay as a checkmark with a toast (the first video).
I don't think the checkmark changing back (second video) is necessary because it can create some buggy behaviour, and I don't think it looks as good.

I fixed the buggy behavior and made the checkmark change back, it makes way more sense

Thank you for the new plugin!
