Renumber, rename, etc the files in the videos-list folder

Item 1 to fix: renumber some file names

For the files that are currently numbered < 10, would you be able to renumber, so there is a leading 0 (zero)?
https://github.com/pymc-devs/video-timestamps/tree/main/videos-list

Why we are doing this: the list of files in that folder will then automatically sort in numerical order

Example:

• 3-Viola.md ==> 03-viola.md
• etc

Item 2 to fix: remove the following in any file names: parentheses, commas

• 2-Tim,Mikkel,Grigorios.md ==> 02-Tim-Mikkel-Grigorios.md (NOTE: Let's not ever use commas in file names, let's use underscores or dashes)
• 7-Thomas(part2).md (NOTE: Let's not use parentheses in file names. Use underscores or dashes only)
• 13-Pedro,Osvaldo.md ==> do not want commas in file name

Item 3 to fix: file names make consistent with capital/lower case letters

It looks like for the first few I started I used lower case. You used upper case. Let's use lower case.

Example:

• 12-johns-mmm.md

Item 4 to fix: file names make consistent first / last name.

It looks like for the first few I started I used speaker last name. You used their first name. We can keep first name. Can you change the few that I had done and make them first name?

Example:

• 7-Thomas(part2).md ==> 07-thomas.md
• 33-wiecki.md ==> 33-thomas.md (do this way)
