Improve the SPDX ID property documentation

[goneall]

Suggestion to add the following information from the SPDX 2.3 spec:

If the creator does not own their own website, a default SPDX CreatorWebsite and PathToSpdx can be used spdx.org/spdxdocs. Note that the SPDX documents are not currently stored or accessible on this website. The URI is only used to create a unique ID following the above conventions.

Updating the language for SPDX 3.

Suggestion made o the 28 May 2024 tech call.

Where should we put that paragraph?

• in spdxId property page?
• in Getting started?
• others..

Where should we put that paragraph?

I'm thinking both the spdxid property page and the getting started page would be helpful.

Thanks. Need to revise these two to SPDX 3 equivalent, I think:

• CreatorWebsite
• PathToSpdx

@goneall, @bact & @kestewart discussed this in release meeting, and decide that this should be documented in "Using" guide. @goneall will transfer.
