Create security cors doc

[sberyozkin]

Fixes #36509.

This PR promotes the CORS related section as an independent security concept, linked to from both HTTP reference and Security overview docs

🙈 The PR is closed and the preview is expired.

[rsvoboda]

@sberyozkin do you know why the preview deploy failed?

Asking because want to check how the guide is presented on /guides page

[rsvoboda]

References will need to be updated in more places:

git grep -l "#cors-filter"

docs/src/main/asciidoc/openapi-swaggerui.adoc
docs/src/main/asciidoc/resteasy-reactive.adoc
docs/src/main/asciidoc/resteasy.adoc

Sorry, @rsvoboda, I was under impression only one doc was referring to the HTTP CORS section, thanks for reminding all docs have to be checked (those links would still work since HTTP section is still there, the only problem, users will need to click on another link from there, so yes, let me handle these links)

[sberyozkin]

@rsvoboda This is done, note http-reference.adoc#cors-filter will now be a more precise check if some old references are still there, all is clear now

Not sure though why surge is failing to publish

[rsvoboda]

https://quarkus-pr-main-36541-preview.surge.sh/version/main/guides/ reports Unavailable

First line of the guide is shown on /guides page. This CORS guide has quite long first sentence, that's why it would be good to check it.

@gastaldi @gsmet did you notice troubles with surge.sh recently?

[gastaldi]

@rsvoboda not recently. I had some trouble in the past when the payload is bigger than the limit supported in surge.sh, which I reported in #35660

[sberyozkin]

@rsvoboda

This CORS guide has quite long first sentence, that's why it would be good to check it.

It was immediately starting from a link to the Mozilla docs, so I removed it, may be it will help for surge to succeed

✔️ The latest workflow run for the pull request has completed successfully.

It should be safe to merge provided you have a look at the other checks in the summary.

[sberyozkin]

@rsvoboda surge did not publish again, not sure why, shall we merge it if you are otherwise happy ? I'd not mind the Doc team having a quick look though

[rsvoboda]

@sunayna15 can you have somebody from the team to look into this? We may merge it soon, docs feedback can be addressed in separate pull request.

@rsvoboda @sberyozkin @sunayna15 Let me have a look on this content. Will create a new PR if needed.
