Global json schema (auto versioning)

[jkellerer]

This PR:

• Generates a JSON schema that redirects to versioned schemas based on version and global.restic-version properties (see also SchemaStore).
• Adds an URL for the schema: https://creativeprojects.github.io/resticprofile/jsonschema/config.json
• Fixes generate --config-reference filename
• Simplifies config-1 schema files (schema in additionalProperties instead of via regex matching with negative lookbehind)

The is the first step to add the schema to the schemastore catalog (we need a single schema for this) and is also more convenient if the URL doesn't need to be changed 😀

After some adjustments it works well for YAML and JSON now. "Even better TOML" doesn't support if/then/else, but without it, YAML and JSON report errors incorrectly, since not setting a version is also an error when only using implication and it is the first and only reported error in this case.

One improvement for "Even better TOML" however is that the updated version-1 schema now also works correctly. Previously it didn't support profile commands due to the lack of full regex support in the editor plugin.

For testing with local references, run:

SCHEMA_BASE_URL="http://localhost:1313/resticprofile/jsonschema" \
resticprofile generate --config-reference contrib/templates/config-schema.gojson > docs/static/jsonschema/config.json

Auto selection then works with:

# yaml-language-server: $schema=http://localhost:1313/resticprofile/jsonschema/config.json
version: "2"

global:
  restic-version: "0.15"

This looks good to me, thanks for this PR 👍🏻

I was trying the new configuration locally but it seems that it doesn't recognise the version 2. Am I doing something wrong?

[jkellerer]

Might be due to implication. While most examples indicate that it should be fine to use it for versioning, I think it needs to be updated to select all versions first using if/then/else and only when this validates, choose a schema for the rest of the document. Otherwise editors will always struggle with priority of errors (or fail to select a different schema).

Will update the template.

Thanks!

I had a quick look at the JSON schema specs and hmmm it does look cutting edge 😐
