@sberyozkin You're welcome to question or push back on any of the proposed changes.
I went a little farther this time, trying to interpret and fix some ambiguous items.
Let me provide some context about these changes so you can review them effectively.

• I noticed backticks (" ` ") around some items that didn't need them.
  • We use backticks to format object names, file paths, commands, output, and entered values as monospaced text. For example:

  `quarkus.oidc.auth-server-url` is
  

  • We generally leave proper names, such as the names of features, unformatted. For example, "the Dev Services For Keycloak feature".
  • We use asterisks to bold UI elements that users click or interact with. For example:

  Click the *Keycloak provider* link.
  

I noticed that, in the text, the labels of some UI elements such as button labels in the text didn't match the labels in the images. I revised the text to match the the images. This might be wrong and we might need to update the images to match the text instead. For example:

• the *OpenID Connect* card
• Click the *Keycloak provider* link.
• so choose the *With Access Token* option,
• Choose the *With ID Token* option in such cases.

@sberyozkin Some other changes you might notice:

• I transformed future tense ("will") to present tense. The future tense can create comprehension problems, especially for users with specific linguistic backgrounds and during localization.
• I converted titles to use sentence case: Lower case except for proper names.
• I replaced "may" with other words to reduce comprehension/localization problems.

I'll be happy to explain or simply reverse any changes (or types or changes) that you request.
Thank you for your thoughtful reviews!

Perfect cleanup, @rolfedh, thanks, a couple of minor suggestions is proposed

Thanks again, @sberyozkin. I've applied your suggestions. I believe this PR is ready for merge.
I also fixed a small typo in security-openid-connect-client-reference.adoc left over from a comment in another merged PR.

@rolfedh: I completed peer review with some comments for your consideration - mainly some capitalization/terminology questions, for example "Dev Services for Keycloak" and also some queries on some text ambiguities.

@sheilamjones, @sberyozkin: I've applied Sheila's suggestions to the file. If you both approve, this PR should be ready to merge.
