fix: correct malformed YAML in ci-build.yml Configure Maven settings step (#1368)

The first three PowerShell lines in the 'Configure Maven settings' step
were at column 0 instead of being indented into the 'pwsh: |' block
scalar, which broke YAML parsing. Indent them to align with the rest of
the script block.
