Prepare release v1.54.0

[sfc-gh-aling]

Automated release cut by /release-cut. Target version: v1.54.0.

Review checklist (cut sanity + release-notes approval):

• Release notes / Changelog Update Approval from Product Manager (Qinyi Ding)

• Version bump correct (for a hotfix, curate the CHANGELOG entries under the new header)

• Dependency alignment setup.py <-> recipe/meta.yaml (verify manually) — no runtime dep changes in 1.54.0

• AST goldens: only client_version bumped; regenerate with the monorepo Unparser only if AST-generation logic changed (out of scope here)

• If adding any arguments to public Snowpark APIs or creating new public Snowpark APIs, I acknowledge that I have ensured my changes include AST support.

• I acknowledge that I have ensured my changes to be thread-safe

(This PR only bumps version.py/recipe/meta.yaml/CHANGELOG.md and AST-golden client_version fields for the v1.54.0 release cut — no new public API arguments or thread-safety-relevant changes.)
