docs: add editorial summaries for Walrus release notes

[reemsabawi-mystenlabs]

Description

Adds editorial-style summaries for the Walrus Platform release notes, one
markdown file per version under docs/editorial/ (66 versions, v1.10.0
through v1.50.0). Each file has title, description, and keywords
frontmatter, a network and date line, and a 1-2 sentence summary
highlighting the most important additions or fixes for that version. The
four versions with no user-facing notes are included with a short
maintenance-release summary.

Walrus Memory and Blog entries are not included in this PR and can be added
in a follow-up.

Test plan

Documentation-only change; no code affected. Verified locally that all 66
files were generated with valid frontmatter and that prose is style-compliant
(Testnet and Mainnet capitalized, no em dashes, no Latin abbreviations,
keywords present on every file). Rendered output should be confirmed in the
docs site preview.

Release notes

Check each box that your changes affect. If none of the boxes relate to your changes, release notes aren't required.
For each box you select, include information after the relevant heading that describes the impact of your changes that
a user might notice and any actions they must take to implement updates. (Add release notes after the colon for each item)
