[JStickler]

What this PR does / why we need it:

Makes small updates to the Structured Metadata and Query Acceleration topics to support the Loki 3.3 version of Query acceleration with Blooms and the GA of Explore Logs.

This PR must be merged before a backport PR will be created.

LGTM!

The backport to release-3.3.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new branch
git switch --create backport-15028-to-release-3.3.x origin/release-3.3.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x 469b54e3d58807d4bc24e4d247a2a205036b0954

When the conflicts are resolved, stage and commit the changes:

git add . && git cherry-pick --continue

If you have the GitHub CLI installed:

# Push the branch to GitHub:
git push --set-upstream origin backport-15028-to-release-3.3.x
# Create the PR body template
PR_BODY=$(gh pr view 15028 --json body --template 'Backport 469b54e3d58807d4bc24e4d247a2a205036b0954 from #15028{{ "\n\n---\n\n" }}{{ index . "body" }}')
# Create the PR on GitHub
echo "${PR_BODY}" | gh pr create --title 'docs: update topics for Blooms (backport release-3.3.x)' --body-file - --label 'size/M' --label 'type/docs' --label 'backport' --base release-3.3.x --milestone release-3.3.x --web

Or, if you don't have the GitHub CLI installed (we recommend you install it!):

# Push the branch to GitHub:
git push --set-upstream origin backport-15028-to-release-3.3.x

# Create a pull request where the `base` branch is `release-3.3.x` and the `compare`/`head` branch is `backport-15028-to-release-3.3.x`.

# Remove the local backport branch
git switch main
git branch -D backport-15028-to-release-3.3.x
