[docs-scanner] Incomplete variable in Circle CI login command

[github-actions]

File: content/manuals/build-cloud/ci.md

Issue

The Circle CI example contains an incomplete variable name in the docker login command (appears twice in the file):

- run: echo "$DOCKER_ACCESS_TOKEN" | docker login --username $DOCKER_ --password-stdin

The variable $DOCKER_ is truncated and should be $DOCKER_ACCOUNT.

Why this matters

Users copying this Circle CI configuration will get a login error because $DOCKER_ is not a valid variable name. The command will fail with authentication errors, preventing builds from running.

Suggested fix

Change both occurrences (in the build_push and build_cache jobs) from:

- run: echo "$DOCKER_ACCESS_TOKEN" | docker login --username $DOCKER_ --password-stdin

to:

- run: echo "$DOCKER_ACCESS_TOKEN" | docker login --username $DOCKER_ACCOUNT --password-stdin

This matches the pattern used in all other CI examples in the same file.
