Fix example configuration in README.md

[mark-strasser-nnl]

The example configuration file (host param) in README.md is incorrect and causes the server to abort on startup.

LocalPackageServer.jl/README.md

Line 34 in d1b7524

host = "localhost"

Behavior

Aborts with error on startup.

Expected behavior

Server should start normally with the example configuration.

Error message

julia --project bin/run_server.jl ../localpackageserver-configs/config.toml
┌ Info: server listening on localhost:8000
└ Dates.now() = 2024-05-10T17:09:50.356
ERROR: LoadError: ArgumentError: invalid base 10 digit 'l' in "localhost"

Suggested fix

Update the example in README.md to state host = "127.0.0.1".
