Align schema commands with public schema endpoints

[ptpaterson]

issues: FE-6178, FE-6233

Problem

We've published the schema API, but don't use it the same way in the commands, and are not consistent between commands.

Solution

Following the published spec

• use format instead of diff URL param.
• do not use force. version is optional.

BONUS: fix .gitignore lines for fauna config files

Result

No change in behavior, but the code is internally consistent between commands and the published API.

Testing

We don't have integration tests, so I am a little paranoid about changing the schema endpoint calls. I ran each command with old and new code. The fauna commands are for using the current main branch, and ./src/user-entrypoint.mjs is for using this branch. schema status calls are sprinkled in with the context.

schema pull

schema push

schema abandon

schema commit

schema diff
