Write out correlations when --create-matrices doesn't include "all"

[tsalo]

Closes none, but addresses a bug identified in https://neurostars.org/t/filenotfounderror-no-bold-data-found-in-allowed-spaces-fslr/30968.

Changes proposed in this pull request

• Set config.execution.output_correlations to True when exact scans are provided through --create-matrices, but "all" is not included.

Maybe I can just force dcan_correlation_lengths to be ["all"] for linc mode and drop output_correlations?
