feat(swap): import .md files and webp transition from myst/current

Selective import from origin/myst/current (cf9c9b34):
- Add/update 255 .md files (full MyST conversion plus webp ref updates)
- Delete 175 PNG/JPG from docs/_static/images (webp twins already present)
- Delete 5 autotest topology.png (webp twins already present)

Preserved on swap (untouched):
- All .rst files (incremental swap pattern)
- conf.py, _ext/, _include/*.txt, .gitignore
- 115 canary md-*.md files
- 7 superpowers/specs/*.md design docs
- Logos vyos-logo.png / vyos-logo-icon.png (referenced by conf.py)

+# DHCP Relay trough GRE-Bridge
+
+```{eval-rst}
+| Testdate: 2023-05-11
+| Version: 1.4-rolling-202305100734
+```
+
+This simple structure shows how to configure a DHCP Relay over a GRE Bridge
+interface.
+
+## Topology
+
+The topology has 3 VyOS routers and one client. Between the DHCP Server and
+the DHCP Relay is a GRE tunnel. The `transport` VyOS represent a large
+Network.
+
+```{image} _include/topology.webp
+:alt: Ansible Example topology image
+```
+
+
+## Configuration
+
+First, we configure the transport network and the Tunnel interface.
+
+Transport:
+
+```{literalinclude} _include/transport.conf
+:language: none
+```
+
+DHCP-Server
+
+```{literalinclude} _include/dhcp-server.conf
+:language: none
+:lines: 1-8
+```
+
+DHCP-Relay
+
+```{literalinclude} _include/dhcp-relay.conf
+:language: none
+:lines: 1-8
+```
+
+After this, we need the DHCP-Server and Relay configuration.
+To get a testable result, we just have one IP in the DHCP range.
+Expand it as you need it.
+
+DHCP-Server
+
+```{literalinclude} _include/dhcp-server.conf
+:language: none
+:lines: 9-13
+```
+
+DHCP-Relay
+
+```{literalinclude} _include/dhcp-relay.conf
+:language: none
+:lines: 9-10
+```
+
+
+## Test the result
+
+Ping the Client from the DHCP Server.
+
+```none
+vyos@dhcp-server:~$ ping 192.168.0.30 count 4
+PING 192.168.0.30 (192.168.0.30) 56(84) bytes of data.

+```
+
+And show all DHCP Leases
+
+```none
+vyos@dhcp-server:~$ show dhcp server leases
+IP Address    MAC address        State    Lease start          Lease expiration     Remaining    Pool        Hostname
