Include files with names starting with `YYYY-MM-DD`

[thephm]

md_interactions.py script only includes files with names YYYY-MM-DD.md but sometimes I have multiple files on the same day for the same person, e.g. a file with tags: email and another with tags: email. I usually have the chat files named with YYYY-MM-DD.md and the email files named with YYYY-MM-DD - email.md. With this improvement, all of them would be embedded in the Person's profile file body within the ## Notes section.
