Add in section on Progress log guidance

[octaviacogher]

• Could we pls add in a section on progress log guidance onto the handbook. Again, this could come under an existing section or be a newly created one.
• Brief description about the purpose of progress logs, what is involved, when they need to be completed and why and when they will receive feedback
• May be worth differentiating between Skills Bootcamp and Fulltime programme
• Guidance could include the following taken from Apprenticeship handbook:

'During this training, apprentices will all be required to fill in a [progress log](https://github.com/fac28/progress-log/tree/main).

The purpose of the progress log is to enable apprentices to reflect on their learning week by week, identify strengths and areas for development, and to receive feedback on their progress from the Course Facilitators in order to improve.

This progress log must be updated every Friday as a reflection activity on the previous week's learning outcomes and ready for review by Monday morning. '
