firstMile: InfluxCLI Onboarding - Install Dependencies - MAC OS

[Luckette]

ACs
- Install Dependencies page should include three tabs underneath the "Install Dependencies" text specific to the user's operating system (MAC OS, WINDOWS, LINUX). See Figma
- Depending on which OS tab the user clicks, the install information below will change accordingly. The selected Tab should highlight blue and the text should be white. 
- For MAC OS, the next sub-step on the Install Dependencies page should be "Use Homebrew" with the copy code snippet "brew install influxdb-cli"
- Text underneath the Homebrew code snippet should be "If you prefer to manually download and install the CLI package, follow our documentation."
- The word "documentation" should be hyperlinked (https://docs.influxdata.com/influxdb/cloud/tools/influx-cli/)
- The next sub-step in the MAC OS flow for Instal Dependencies should be "Useful InfluxCLI Commands"
- Text underneath "Useful InfluxCLI Commands" should be "To invoke a command, use the following format in the command line: influx <command>" (See Figma)
- In the "Useful InfluxCLI Commands" sub-step/section should be a table of useful commands and their definitions. (bucket, export, help, help <command>, query, and write)
- Underneath the table of useful commands should be the following text and link "A full list of InfluxCLI Commands is available in our documentation." The word documentation should be hyperlinked to:(https://docs.influxdata.com/influxdb/cloud/reference/cli/influx/)        

Dev Notes

• If URL to the InfluxCLI is used, use the URL with "latest" in the title - assuming that the edge/cli team finished their ticket (firstMile Onboarding - InfluxCLI - Update all OS downloads to include a URL with "latest" in the title - route to latest version influx-cli#394)
