Provide a SARIF v2.2 Seed Prose by Transcribing the v2.1.0 Errata 01 Prose to Markdown

[sthagen]

Work in progress at https://github.com/sthagen/oasis-tcs-sarif-spec/blob/versioned-spec-folders/sarif-2.2/prose/sarif-v2.2-editor-draft.md (in fork)

Using some fresh markdown boilerplate to fill in a best effort transcription of the
SARIF v2.1.0-os-errata-01 candidate prose.

We may want to refactor or change some "things" of the 2.1 era to ease future work (and reading):

• reduce the linkage (there are approx. 1400 §#.#.# links for a tad more than 200 pages which makes on the average 7 such opaque links per page) and make more links have a "speaking" link text
• externalize the JSON examples as example files (inside the /sarif-2.2/example/ folder)
• explicitly name all artifacts on file level
• rewrite tables with two columns as definition lists
• migrate to two slot versioning (2.2) for the spec
• ...
