fix --soft-file syntax

[ljuboops257]

in reference below the --soft-fail should have formated so that looks like --soft-fail=${INPUT_SOFT_FAIL_COMMENTER}
with current code version we can't enable action to fail pipeline if error occur

tfsec-pr-commenter-action/entrypoint.sh

Line 66 in 5b483d4

tfsec --out=${TFSEC_OUT_OPTION} --format="${TFSEC_FORMAT_OPTION}" --soft-fail ${TFSEC_ARGS_OPTION} "${INPUT_WORKING_DIRECTORY}"
