Documentation: Unclear/misleading URL open in yarn dev process

[Warr1024]

Describe the bug

https://github.com/butlerx/wetty/blob/main/docs/development.md does not make it clear what URL to open to access the locally-running server, and the yarn dev script actually attempts to xdg-open http://localhost:8080/ (some built-in default?) which is incorrect and confusing.

To Reproduce
Steps to reproduce the behavior:

1. Check out git src.
2. yarn
3. yarn build
4. yarn dev

Expected behavior
Once WeTTY is running locally, any one of the following happens:

• the web UI is opened for me automatically by script, or
• I follow clear and correct instructions on how to open it, either output by the script, or in the development.md docs.

Actual behavior

• https://github.com/butlerx/wetty/blob/main/docs/development.md does not say anything about opening the web UI once it's running.
• yarn dev attempts to xdg-open http://localhost:8080/, i.e. the incorrect URL. Apparently something else is listening on this URL, but it's not serving WeTTY.
• yarn dev does not attempt to open http://localhost:3000/wetty, i.e. the correct URL.

Additional context
Luckily I was able to figure out what I'm supposed to be doing was by parsing the [1] info: Starting server {"base":"/wetty/","label":"Wetty","port":3000,... log line, but it would be far better if new prospective devs faced fewer obstacles getting started.
