Fix HTTP casing + update links to license-list-XML repo

[bact]

SPDX License List matching guidelines and templates

• Use "HTTP" and "HTTPS" for protocol names; Use "http://" and "https://" for URI schemes
  • Same changes reviewed and merged in Add missing anchors B.6.4, B.15.3; Swap HTTP cases license-list-XML#2537 and Update license-list-XML URLs, update "The Linux Foundation" license-list-XML#2545 - this PR is to matched similar changes
• Use "SPDX License List" caps style as it is a proper noun and stylized like that consistently in https://spdx.org/licenses/
• Keep page title and navigation bar title match
• Use a versioned link of resources from license-list-XML repo
  • https://github.com/spdx/license-list-XML/blob/v3.24.0/schema/ListedLicense.xsd
  • https://github.com/spdx/license-list-XML/blob/v3.24.0/DOCS/license-fields.md
  • Also to keep it consistent with a ref in licenseXml - updated with licenseXml: Link license-list-XML to a specific version (v3.24.0) spdx-3-model#819

This will fix #1068 and resolve #1070

@swinslow If v3.25.0 will eventually available soon in these exact URLs:

• https://github.com/spdx/license-list-XML/blob/v3.25.0/schema/ListedLicense.xsd
• https://github.com/spdx/license-list-XML/blob/v3.25.0/DOCS/license-fields.md

I think it's possible to put them in advance to the spec. I'm happy to modify this PR for that.
(and also update licenseXml, which is currently already linked to v3.24.0 by spdx/spdx-3-model#819)

But apart from the URLs, do you like to changes anything here please? Thank you.
