Add Legacy Text Template format section back to the Matching Guidelines

[bact]

standardLicenseTemplate and standardAdditionTemplate still need the Legacy Text Template.

See discussion in spdx/spdx-3-model#747 (comment)

• Use source from https://github.com/spdx/spdx-spec/blob/development/v2.3.1/chapters/license-matching-guidelines-and-templates.md https://github.com/spdx/license-list-XML/blob/main/DOCS/license-matching-guidelines-and-templates.md
• Adjusted anchor numbering, links
• Add missing anchors: C.6.4
• Add internal link to guidelines
• Use `...` around some special characters to differentiate

@jlovejoy, @swinslow - here's the PR that is adding it back, that was referenced yesterday.

[zvr]

The source where we copy the whole annex should be https://github.com/spdx/license-list-XML/blob/main/DOCS/license-matching-guidelines-and-templates.md and not some ancient version from SPDXv2.

@zvr I was using v2.3.1 only because it's the latest version before v3.0 (which doesn't has this file). I was not aware of license-list-XML, so thanks for the pointer.

I just have checked the Legacy Text Template format section from both sources (license-list-XML and v2.3.1), they are identical.

[zvr]

@bact have you checked that the complete file is identical (not only the last section) ?

[bact]

@zvr this PR is based on the existing file. The last section is added. Other sections are added by PR #968.

I haven't look very carefully all of them, only headings (that's how I spotted the missing "C.6.4" anchor). I can check them all again.

[bact]

Done. Every sections in the source of license-list-XML and v2.3.1 are identical.

Through the scan, found two spots in "HTTP Protocol" section that may need changes:

• Protocol names (HTTP and HTTPS) should be in UPPERCASE
• The URL schema names at the first part of URL ("http://" and "https://", which will be the actual texts to be compared) should be in lowercase
• Open a PR Add missing anchors B.6.4, B.15.3; Swap HTTP cases license-list-XML#2537 there in license-list-XML repo for people there to decide. Text in this PR is unchanged.

Also one typo found (introduced be myself during the link format conversion), will fix that.

[jlovejoy]

@zvr - now I'm confused... are we keeping the matching guidelines in the license list repo? we definitely should not have them in two places!
