Fix: broken tests due to real-world changes

The following tests were breaking before the changes in this commit:

```
FAIL in (latest-version-test) (dep_add_test.clj:9)
expected: (= "1.11.1" (neil/latest-stable-mvn-version (quote org.clojure/clojure)))
  actual: (not (= "1.11.1" "1.11.2"))

FAIL in (dep-upgrade-test-using-git-tags) (dep_upgrade_test.clj:71)
deps can be added with --tag
expected: (= "v2022.03.08" (:git/tag original))
  actual: (not (= "v2022.03.08" "v2024.03.13"))

FAIL in (dep-upgrade-test-using-git-tags) (dep_upgrade_test.clj:79)
deps with :git/tag coords upgrade to latest tags
expected: (= "v2022.03.08" (:git/tag original))
  actual: (not (= "v2022.03.08" "v2024.03.13"))

FAIL in (dep-upgrade-test-using-git-tags) (dep_upgrade_test.clj:84)
deps with :git/tag coords upgrade to latest tags
expected: (not= (:git/tag original) (:git/tag upgraded))
  actual: (not (not= "v2024.03.13" "v2024.03.13"))
```

The reasons for this are:

1. The latest stable version of `org.clojure/clojure` is `1.11.2`
2. Running `git/find-github-tag 'clj-kondo/clj-kondo "v2022.03.08"`
returns `nil`, which makes `neil` fetch the latest github tag instead.

To fix this, we:
1. Bump the latest stable version for Clojure in tests to 1.11.2
2. Bump the tag version used for `clj-kondo/clj-kondo` to
`v2024.03.13` (latest) in `dep add` tests.
3. Bump the tag version used for `clj-kondo/clj-kondo` to
`v2024.03.05` (not latest, but exists) in `dep upgrade` tests.
