Silent error in trestle author jinja on incorrect file names

Describe the bug

Trestle author jinja was fed incorrectly capitalized file names.

To Reproduce

make ssp-markdown

trestle author jinja -i ACME_platform_ssp.md.jinja -ssp ACME_SSP -p ACME_int_guidance -o ACME_platform_ssp.md -bf "[.]" -vap "ACME Assigned:" -vnap "Assignment:"
should be

trestle author jinja -i acme_platform_ssp.md.jinja -ssp ACME_SSP -p ACME_int_guidance -o acme_platform_ssp.md -bf "[.]" -vap "ACME Assigned:" -vnap "Assignment:"
