fix(clipboard): when click the copy button the data is not copied wit…

…h `v-clipboard:copy`

Error:
- When the copy button is pressed a success alert is displayed, but the console message `Clipboard input is empty` appears.
- This message appears despite fixing the issue, it is a package problem and is not fixed at this time.

Reason:
- The `v-clipboard:copy` directive of the `vue-clipboard2` package does not exist in the `v-clipboard` package.
- When using the `v-clipboard` directive of the `v-clipboard` package to execute a method (`copyData`), it no longer returns the copied value (`json`) by itself, as towards the `v-clipboard:copy` directive of the `vue-clipboard2` package.

Solution:
- Replace the `v-clipboard:copy` directive with the `v-clipboard` directive.
- The `copyData` method needs to use `this.$clipboard.copy(value)` or `Clipboard.copy(value)` to copy the value.
In this case, since the package has been imported globally, `this.$clipboard.copy(value)` would be used, but with `setup` we cannot use `this`. So import `Clipboard` from `v-clipboard` package  into the component and use `Clipboard.copy(value)` instead.
You need to globally import the `v-clipboard` package to use the `v-clipboard` directive.
