Add installer attributes for name, version, platform, and type to .constructor-build.info

[stacynoland]

Description

This PR adds attributes to the .constructor-build.info file for persistent storage:

• installer_name
• installer_version
• installer_platform
• installer_type

This information is being stored so other services, such as telemetry, can find details about the installer used.

Checklist - did you ...

• Add a file to the news directory (using the template) for the next release's release notes?
• Add / update necessary tests?
• Add / update outdated documentation?

	out["installer_name"] = info.get("installer_name", "Unknown")
	out["installer_version"] = info.get("installer_version", "Unknown")
	out["installer_platform"] = info.get("installer_platform", "Unknown")
	out["installer_name"] = info.get("name", "Unknown")
	out["installer_version"] = info.get("version", "Unknown")
	out["installer_platform"] = info.get("_platform", "Unknown")

I looked at the keys again that I mentioned yesterday and I realized that was incorrect. I added this suggestion which should be accurate:

1. name from construct.yaml
2. version from construct.yaml
3. _platform is set via main.py
4. installer_type also set via main.py

I also wonder if we should simply have empty strings as default but no strong opinion, I guess the consumer of this data might have an opinion of this.
Perhaps also installer_name and installer_version should not even have a default since something must be fundamentally wrong if it not set.

They're all guaranteed to be set. I think a simple get() without default values is good here - in the unlikely case that a value isn't set, we'd get null instead of a special string in the JSON file. Empty string is a good alternative, which I'd prefer over "Unknown".

[marcoesters]

I think we should use a separate file to not conflate installer and build environment information. I would also like to see the changes be covered by a test - I recommend just modifying an existing one.

[marcoesters]

I'm not sure about whether to re-use that file. The file contains information about the build process and contains information on conda, python, etc. from the build environment. Adding information of the installer could imply that these are the version of conda, python, etc. that are packaged in the installer.

I think a separate file makes more sense.
