Update Project Profile: Not Today (Update Project's Description)

### Overview
We need to keep project information up to date so that visitors to the website can find accurate information.

### Action Items
- [ ] In your IDE, open the `_projects/nottoday.md` file.
- [ ] Observe the existing syntax of the front matter block [^1] in the file.
- [ ] Find the `description` variable and change the following:

**From:**
```
Not Today - the self-defense against suicidal thoughts app is intended to help people wait out periods of suicidal thinking without acting on their thoughts.

```
**To:**
```
Not Today is an app designed to help people experiencing suicidal thoughts make one immediate decision: not today. Rather than asking someone to solve everything in the middle of a crisis, the app helps them wait out periods of suicidal thinking without acting on those thoughts. Users can leave messages for their future selves, including voice recordings, photos, text, links, and videos, set wellbeing check-ins, and quickly access suicide-prevention and crisis support by phone or text.

```
- [ ] Verify the changes by viewing the following in your local environment with Docker and include before and after screenshots with your pull request:
- [ ] Not Today page [^2]
- [ ] the project's card on the Projects' page [^3]

### Resources/Instructions
[^1]: [Info about the front matter block](https://jekyllrb.com/docs/front-matter/)
[^2]: Project detailed info page URL: https://www.hackforla.org/projects/not-today
[^3]: Projects page URL: https://www.hackforla.org/projects/

Open _projects/nottoday.md and inspect its front matter, then locate the description variable. Update it to the wording in the issue and run the website locally with Docker to verify the Not Today page and Projects page card. Done means the description appears correctly in both views and before-and-after screenshots are included with the pull request.
