chore: ensure schema-embed.json is accurate when examples are generat…

…ed (#227)

The example generator script includes some code to replace the current
Equinix Pulumi plugin version in generated examples with `< 1.0.0` (or
the equivalent per language). The script uses `.pulumi/bin/pulumictl get
version --language generic` to determine the version number that should
be replaced. However, the examples are not necessarily generated to
reference that plugin version. The version referenced in examples
appears to come from
`provider/cmd/pulumi-resource-equinix/schema-embed.json`.

This adds `build_schema` as a dependency of the `only_provider` Make
task. The `only_provider` task is already a dependency of the `examples`
task and the files produced by `build_schema` are necessary for
`only_provider`.

This change ensures that the schema files are up-to-date before examples
are generated.
