Create Wiki Page: "Pep Talk"

### Overview
Create a Pep Talk wiki page explaining how to deal with not knowing the language/tech stack so that new developers don't get discouraged and quit.

### Action Items

- [ ] We are currently in the process of moving the old wiki to the new [website-wiki repo](https://github.com/hackforla/website-wiki), so we will not be making any changes or additions to the old wiki at this time. Thus, we will be adding wiki content through a different process now. Read [How to Contribute to the Wiki](https://github.com/hackforla/website/wiki/How-to-Contribute-to-the-Wiki)

The pep talk wiki page should include the following:

- [ ] Examples of how to use current knowledge and applying it. For example, if you understand how if statements work in a different programming language, in Liquid it is similar.
- [ ] Not knowing the programming languages or tech stack is normal. It usually occurs for developers starting a new job and you learn as you go.
- [ ] That you should spend some time understanding the existing codebase or understanding a new programming language/technology before you start coding for an issue.
- [ ] Employers often hire people who don't know a specific language if you are able to communicate on a resume and during the hiring process that you are willing to get up to speed on a new language, because many concepts are similar enough across languages.
- [ ] Reference the [HFLA Architecture wiki](https://github.com/hackforla/website-wiki/blob/main/docs/Site-Architecture/Hack-for-LA's-Site-Architecture.md) that explains the sites technologies
