Add Access Needs reminder to first day and/or onboarding module on ITP

**Which module(s) and week(s) does this change affect?**
Module(s): [Welcome to Code Your Future](https://programming.codeyourfuture.io/welcome/) / [Onboarding](https://programming.codeyourfuture.io/onboarding/sprints/1/day-plan/)
Week(s): 1 / 1

**What is the work that needs to be done?**
Adding reminders to talk about the basic Access Needs requests so everyone knows where these things are:
- Prayer room location
- Toilers: where they are and if there are any single-sex/neutral toilets available
- Wheelchair access
- Agenda: is published on our Curriculum
- Instructions are written down: they are all published on our Curriculum
-

**Why is this work important to do?**
We ask for people's access needs, but in the middle of the chaos of everything new happening, it's good to have a reminder for volunteers and the community to talk about these basic access needs.

**Who might need to know about this change?**
