feat: copy package name button

[WilcoSp]

Added a button to copy the package name at the package page, this makes it for example easier to create an install command in the cli with multiple package.

I've also adapted the AppTooltip component to a base component so that also the AnnounceTooltip component could be made.
With the AnnounceTooltip component currently only shows when the package name is copied like in the screen shot below but it can in the future be used for other purposes.
