[Repo Assist] Release prep: update 7.0.0 change log with recent bug fixes

[github-actions]

🤖 This is an automated draft PR from Repo Assist, an AI assistant.

Summary

Updates the RELEASE_NOTES.md to add the bug fixes and breaking changes that were merged since 6.6.0 but were missing from the 7.0.0 - Unreleased section. Also restructures the 7.0.0 section with New Features and Bug Fixes sub-headings for clarity.

Changes in RELEASE_NOTES.md

The following merged PRs were not yet recorded under 7.0.0 - Unreleased:

Fix	Issue(s)	Merged PR
Singularization of *ases words (e.g. databases → database)	#1508	#1524
Register CodePagesEncodingProvider on .NET 6+ for #r "nuget:" users	#1453	#1612
JsonConversions.AsDecimal now handles JsonValue.Float (exponential notation)	#1230	#1608
JsonValue.Float serialization: whole-number floats now output 100.0 not 100	#1356	#1606
HtmlNode.ToString: whitespace inside <pre> elements now preserved	#1509, #1223	#1605
CSV schema parsing: column names with parentheses no longer corrupt type annotations	#946	#1604

The singularization change is flagged as breaking (existing code using *asis type names for *ases words will need updating), which is one of the reasons this is being tracked as 7.0.0.

Test Status

This PR only modifies RELEASE_NOTES.md (documentation) — no build or test run required.

Notes for Maintainers

• There are also two still-open Repo Assist PRs: [Repo Assist] Fix #1383: Throw NotSupportedException for unrecognized CSS pseudo-classes #1613 (CSS pseudo-class fix) and [Repo Assist] Update test/build dependencies: FAKE 6.1.4, NUnit 3.13.3, FsUnit 4.2.0, FsCheck 2.16.6 #1614 (dependency updates) — once merged, those items should also be added to 7.0.0 notes before tagging a release.
• The last published GitHub release is 6.3.0 (September 2023). Releases 6.4.0–6.6.0 appear in RELEASE_NOTES.md but have no corresponding GitHub release tags. It may be worth publishing those as releases, or doing a single 7.0.0 release.
• The 7.0.0 bump (vs a 6.7.0 minor) is driven by the singularization breaking change ([JsonProvider] Plural word 'purchases' renamed as Purchasis in the .NET typespace #1508) and the DateOnly/TimeOnly feature. Maintainer discretion on exact version.
