[bug] docs claim git fetch --deepen doesn't fetch tags, but it does

The docs for git fetch `--depth` say:

And shallow.txt says:

However it seems like this has been implemented, and the corresponding docs should instead declare that tags for the fetched commits are fetched. It certainly looks that way from my testing:

``` $ git --version git version 2.32.1 (Apple Git-133)

$ git clone --depth=1 https://github.com/git/git Cloning into 'git'... # < ... >

$ cd git

$ git describe --tags --always 1bcf4f6

$ git fetch --deepen 8
# < ... >
Unpacking objects: 100% (12/12), 9.02 KiB | 9.02 MiB/s, done.
From https://github.com/git/git
* [new tag] v2.31.3 -> v2.31.3
* [new tag] v2.32.1 -> v2.32.1
* [new tag] v2.32.2 -> v2.32.2
* [new tag] v2.33.2 -> v2.33.2
* [new tag] v2.33.3 -> v2.33.3
* [new tag] v2.34.1 -> v2.34.1
* [new tag] v2.34.2 -> v2.34.2
* [new tag] v2.34.3 -> v2.34.3
* [new tag] v2.35.1 -> v2.35.1
* [new tag] v2.35.2 -> v2.35.2
* [new tag] v2.35.3 -> v2.35.3
* [new tag] v2.36.0 -> v2.36.0

$ git describe --tags --always v2.35.3-35-g1bcf4f6 ```

(I get the same results using `git clone --depth` or `git fetch --depth`)

It'd be good to have someone who understands the code confirm this (and what version it was implemented, in case it's accidental, or doesn't always work as expected.

I found a stackoverflow from a couple years ago implying this didn't work at the time, though it doesn't say what git version they were using: https://stackoverflow.com/questions/56477321/can-i-make-git-fetch-a-repository-tag-list-without-actually-pulling-the-commit-d
