[DOC] Modify the IoT Sub-division

[Akshu-on-github]

Proposed Idea(s)

I notice that the IoT sub-division has a lot of IoT and IoT based prefixes - I feel that this is redundant, and may be removed. For example, the original:

- IoT Contactless Covid Testing Booth Automation
- IoT Social Distancing & Monitoring Robot For Queue
- IoT Covid Patient Health Monitor in Quarantine
- IoT based Manhole Detection and Monitoring System
...

May be modified to:

- Contactless Covid Testing Booth Automation
- Social Distancing & Monitoring Robot For Queue
- Covid Patient Health Monitor in Quarantine
- Manhole Detection and Monitoring System
...

Additionally, the hardware required, difficulty level, links to opensource repos or examples, and the like may be added in the form of a dropdown. For example,

<details>
  <summary>Read More</summary>
  <ul>
    ...
  </ul>
</details>

Advantages

• Looks neat and concise
• The details are resented in such a way that the most important points may be easily skimmed
