Removing duplicate Batch Rename from scene-tree menu

[swarnimarun]

I, while working on something came across a this duplicate so thought why not remove it.

@swarnimarun Did this create two entries? It should replace the default one.
This PR removed the batch rename dialog from the menu.
When multiple nodes are selected I would argue that it should use this dialog instead of the default behaviour which can not handle multiple nodes.

This is probably the reason why the batch rename dialog got skipped from the changelog @akien-mga
You can still access it via CTRL+F2.

@bfloch Thanks for pointing it out let me quickly fix it...

[swarnimarun]

@bfloch What's the problem? Cause I am not able to see how it is causing a problem, the place it now makes more sense as the comment says.

[akien-mga]

I also don't see what's the problem.

@Calinou Apparently the Batch Rename scene tree tool is not listed in the changelog yet, see #15928.

[Calinou]

@akien-mga I just added it to the changelog.

[bfloch]

I think I know where my confusion comes from.
If you have child nodes selected it only shows "Rename".

Batch Rename works well for hierarchies, has per level Options etc.
Now I am not sure if that's me messing up since it was so long ago, but I thought it worked at some point.

@Calinou Thanks for the update.
