Editorial: DCQL integration into Section 5

[dbluhm]

While reading through the latest drafts after the introduction of DCQL, we noticed a few places where DCQL could be better integrated into text that existed prior to the introduction.

• Section 5, Paragraph 4 specifically mentions PE, giving an overview of how it's used to request credentials, but fails to mention DCQL
• In Section 5, the lack of a subsection for DCQL makes it easy to overlook that dcql_query is an expected parameter in the Authorization Request.
• Section 5.3 shows an example authorization request with a presenation_definition parameter but not one with dcql_query.
• Section 5.6, Paragrah 2 contains a typo resulting in a bulleted list not getting rendered correctly.
• Section 5.6, Paragraph 4 and Paragraph 5, which suggest possible options for where well-known scope values could be defined, specifically discusses PE but not DCQL.
