Update the Web Developer wiki page

### Overview
As a developer, I want the [Web Developer wiki page](https://github.com/hackforla/website/wiki/Web-Developer) to be up to date and an informative resource for developers interested in joining our team and for current developers on the team. For this issue, we will update the [Web Developer wiki page](https://github.com/hackforla/website/wiki/Web-Developer).

### Action Items
- [x] 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)
- [x] For an example of a good role-based wiki page, see [UI UX Researcher wiki page](https://github.com/hackforla/website/wiki/UI-UX-Researcher)
- [x] Take a look at what is in the [developer pre-work checklist](https://github.com/hackforla/website/issues/new?assignees=&labels=Feature%3A+Onboarding%2FContributing.md%2C+good+first+issue%2C+Ready+for+Milestone&template=pre-work-template--dev.md&title=Pre-work+Checklist%3A+Developer%3A+%5Breplace+brackets+with+your+name%5D). Is there anything on the pre-work checklist that could be useful on the Web Developer wiki page?
- [x] Take a look at the files in our [Wiki](https://github.com/hackforla/website/wiki). Is there anything there that would be good to link to on the Web Developer wiki pages?
- [x] Update the [Web Developer wiki page](https://github.com/hackforla/website/wiki/Web-Developer)
- [x] Include information about issue progression: All developers should progress from two good first issues to small to medium and then another medium or large issue. Afterward, a developer can pick any medium or large size issue to work on.
