### Issue
When installing a server with DNS and DNS over TTL, the DoT forwarder is not added as a forwarder.

#### Steps to Reproduce
1. install a machine with freeipa-server-encrypted-dns package:
```
# dnf copr enable -y @freeipa/freeipa-master-nightly
# dnf install -y freeipa-server-dns freeipa-server-encrypted-dns
```
2. Configure IPA server with encrypted dns
```
# ipa-server-install --domain ipa.test --realm IPA.TEST --setup-dns --dns-over-tls --dot-forwarder "1.1.1.1#cloudflare-dns.com" -a Secret123 -p Secret123 -U
```
3. Check the forwarders with
```
# echo Secret123 | kinit admin
# ipa dnsconfig-show
# ipa dnsserver-show `hostname`
```

#### Actual behavior
The DoT forwarder is not configured as a DNS forwarder.

```
# ipa dnsconfig-show
---------------------------------
Global DNS configuration is empty
---------------------------------
  IPA DNS servers: server.ipa.test
#  ipa dnsserver-show `hostname`
  Server name: server.ipa.test
  SOA mname override: server.ipa.test.
  Forwarders: 127.0.0.55
  Forward policy: first
```

#### Expected behavior
The DoT forwarder should be added to the list of forwarders for the DNS server and appear in the output of `ipa dnsserver-show`

#### Version/Release/Distribution
```
# rpm -q freeipa-server
freeipa-server-4.13.0.dev202502131605+git-0.fc41.x86_64
```

#### Additional info:
Seems to be related to a typo in the code:
in ipaserver/install/dns.py lines [439-440](https://github.com/freeipa/freeipa/blob/018b3d3dc6d26ec50f73aaea675ecfb8813aaea1/ipaserver/install/dns.py#L439-L440):
```
    if not options.forwarders and options.dot_forwarders:
        options.forwaders = [fw.split("#")[0] for fw in options.dot_forwarders]
```
Note the missing r in forw**ad**ers
