[DOCS] Document your CycloneDX properties

[jkowalleck]

Problem Statement

I see that tern uses CycloneDX properties. like here

tern/docs/examples/photon-cdx.json

Lines 26 to 35 in 717ea47

	"properties": [
	{
	"name": "tern:repotag",
	"value": "photon:3.0"
	},
	{
	"name": "tern:os_guess",
	"value": "VMware Photon OS/Linux"
	}
	],

I would love to see a documentation of the CycloneDX property taxonomy used by tern.
Maybe I just missed it? At least it was not linked in the official registry https://github.com/CycloneDX/cyclonedx-property-taxonomy/blob/ed8a972a5e1c925bba05f8865c1ad3219b872c98/README.md?plain=1#L117

Describe the Proposal

Have the CycloneDX properties documented:

• property name
• scope - where the property should be used
• value space - what the value mean

something similar to https://github.com/CycloneDX/cyclonedx-property-taxonomy/blob/main/cdx.md

Steps to Implement Proposal

I guess, the documentation could be done in a regularly updated file in this repo, or even in this repo's wiki.

After publishing your taxonomy, please link them in the CycloneDX Property taxonomy registry.
