[changelog] Backfill v2 alpha changelogs

[Juice10]

Summary

Backfills the pre-Changesets v2 alpha release notes into the package changelogs. The added sections cover the missing alpha.0 through alpha.4 ranges using Changesets-style headings, PR links, commit links, and contributor attribution.

The entries preserve the historical package versions where they differed before fixed-package Changesets releases, including rrweb-player 1.0.0-alpha., rrdom 0.1., and rrdom-nodejs 0.1.*.
