Alternate usage

This binary can be used as a CLI syntax checker for Quadlet files. This can be useful, for example in CI/CD pipeline to verify Quadlets before packaging and later deploying.

Same rule applied for CLI that is also applied for editor syntax checking. The .quadletrc.json file is also used on same way.

Example for usage, that monitor the current working directory:

$ quadlet-lsp check .
nc-db.container     , quadlet-lsp.qsr003, 09.000-09.010, Invalid property is found: Container.Memory
nc-app.container    , quadlet-lsp.qsr003, 08.000-08.010, Invalid property is found: Container.Memory
$ echo $?
4

Binary return with non-zero return code if it find any non information finding.
