Subject: [PATCH] docs(nginx): pass host as received from client (#8690)

# Which Problems Are Solved

The Host header reaching ZITADEL must be the same like it is requested
by the browser, or all sorts of issues arise. However, in the NginX
docs, it is appended by the port.

# How the Problems Are Solved

Port is removed from examples

# Additional Context

- Closes https://github.com/zitadel/zitadel/issues/7804
- Relates to https://github.com/netbirdio/netbird/issues/1395
