chore(deps): update lodash to version 4.17.23 across all packages to fix prototype pollution issue

[andleebsyed]

Description
This PR bumps lodash from 4.17.21 to 4.17.23 in the root workspace and in packages that declare it as a devDependency (slate, slate-dom, slate-history, slate-react).

Why

4.17.23 includes a security fix for prototype pollution in _.unset and _.omit, tracked as CVE-2025-13465 (GitHub advisory). It can also be seen in Snyk Vulnerability Database. Upgrade to 4.17.23 is needed to fix this.

Lodash’s own changelog documents this release:

lodash wiki — v4.17.23 — notes the _.unset / _.omit fix and links the advisory above.

Checks

• The linter passes with yarn lint. (Fix errors with yarn fix.)
• The relevant examples still work. (Run examples with yarn start.)
• You've added a changeset if changing functionality. (Add one with yarn changeset add.)
