Change references to schema `id` and `from_schema` slot in YAML source

[sujaypatil96]

The main YAML source file (currently: https://github.com/GenomicsStandardsConsortium/mixs/blob/main/src/mixs_6_2_for_merge/schema/mixs_6_2_for_merge.yaml) has:

• id: https://w3id.org/mixs-6-2-rc
• from_schema: https://w3id.org/mixs-6-2-rc

This needs to be changed so we're using https://w3id.org/mixs

Note: This will further require modifications to the .htaccess file on w3id.org (https://github.com/perma-id/w3id.org/blob/master/mixs/.htaccess) so that the patterns know where to look for files/artifacts in the new directory structure.

All appearances of the regular expression mixs.6.2, across the repo, have been replaced with plain mixs

• https://w3id.org/mixs redirects to the documentation index page, https://genomicsstandardsconsortium.github.io/mixs/
• https://w3id.org/mixs/mixs.yaml redirects to the nonexistent https://raw.githubusercontent.com/GenomicsStandardsConsortium/mixs/main/model/schema/mixs.yaml

Remove all references to the "vocab endpoint"?

• https://w3id.org/mixs/vocab -> undefined https://genomicsstandardsconsortium.github.io/mixs/https://genomicsstandardsconsortium.github.io/mixs/
• https://w3id.org/mixs/vocab/Soil resolves properly, as does https://w3id.org/mixs/Soil
  • see also discussion about resolving by element name vs element id
• https://w3id.org/mixs/mixs.yaml -> broken https://raw.githubusercontent.com/GenomicsStandardsConsortium/mixs/main/model/schema/mixs.yaml
  • should redirect to https://raw.githubusercontent.com/GenomicsStandardsConsortium/mixs/main/src/mixs/schema/mixs.yaml

should we apply the same kind of redirection for these?

• mixs.schema.json: https://raw.githubusercontent.com/GenomicsStandardsConsortium/mixs/main/project/jsonschema/mixs.schema.json
• mixs.context.jsonld (skip? includes the schema and the contexts file)
• mixs.owl.ttl: https://raw.githubusercontent.com/GenomicsStandardsConsortium/mixs/main/project/owl/mixs.owl.ttl

Because the (expandable) schema source for from_schema is says it is a read-only slot, I am removing all of those assertions.
