`git remote prune <remote>…​` (equivalent to git fetch --prune <remote> except that no new references will be fetched) ignores `fetch.pruneTags` (and `git fetch --dry-run` prints same tag twice)

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

cd '/'; cd '/'; rm --force --recursive -- './test_git'; mkdir "$_"; cd "$_";
mkdir --parents -- './server' './client';
git -C './server' init --bare './repo.git'
git --git-dir='./server/repo.git' --work-tree='.' commit --allow-empty
-m "$((++number))"
git -C './server/repo.git' branch branch1; git -C './server/repo.git'
branch branch2; git -C './server/repo.git' tag tag1; git -C
'./server/repo.git' tag tag2

git -C './client' init './repo'
git -C './client/repo' remote add server 'file://'"$(realpath
'./server/repo.git')"
git -C './client/repo' remote --verbose
git -C './client/repo' config list --local --show-scope --show-origin
git -C './client/repo' branch --list --all --verbose --verbose
git -C './client/repo' tag --list

git -C './client/repo' fetch --all
git -C './client/repo' branch --list --all --verbose --verbose
git -C './client/repo' tag --list

git -C './server/repo.git' branch --delete branch1; git -C
'./server/repo.git' branch branch3; git -C './server/repo.git' tag
--delete tag1; git -C './server/repo.git' tag tag3
git -C './client/repo' remote prune --dry-run server
git -C './client/repo' fetch --prune --dry-run server
git -C './client/repo' config set --local 'fetch.pruneTags' 'true'
git -C './client/repo' remote prune --dry-run server
git -C './client/repo' fetch --prune --dry-run server
git -C './client/repo' config unset --local 'fetch.pruneTags'
git -C './client/repo' config set --local --append
'remote.server.fetch' '+refs/tags/*:refs/tags/*'
git -C './client/repo' remote prune --dry-run server
git -C './client/repo' fetch --prune --dry-run server

git -C './client/repo' remote prune server
git -C './client/repo' branch --list --all --verbose --verbose
git -C './client/repo' tag --list

What did you expect to happen? (Expected behavior)

https://git-scm.com/docs/git-remote says:
`git remote prune <remote>…` is equivalent to `git fetch --prune
<remote>`, except that no new references will be fetched.
so:
`git remote prune <remote>…` should prune tags when `fetch.pruneTags` is `true`.
(`git remote prune <remote>…` should prune tags when
`remote.server.fetch` has `+refs/tags/*:refs/tags/*`.)

`git fetch --dry-run` should print same tag once.

What happened instead? (Actual behavior)

Setting `fetch.pruneTags` to `true` does not make `git remote prune
<remote>…` prune tags.
(`git remote prune <remote>…` prunes tags when `remote.server.fetch`
has `+refs/tags/*:refs/tags/*`.)

`git fetch --dry-run` prints same tag twice.

What's different between what you expected and what actually happened?
