In gitk, we can right-click on the icon of the branch,
and a directory will pop up to provide us with functions
such as "Checkout this branch", "Rename this branch"...,
but we found that the right-click tag icon does not have such
a function , So I learned how to write the branch icon, and
added the following functions "Rename this tag","Remove this tag",
"Copy tag name" to right-click the tag icon. This function is
temporarily supported work on the branch with <=3 tags.
