Google Colab Installation process

This is not an issue but couldn't find a better place to share.

Current README.md has the following code for installing the library

**Code**
```
git clone https://github.com/facebookresearch/segment-anything-2.git

cd segment-anything-2 & pip install -e .
```

This leads to following error when using T4x2 GPU runtime in Google Colab

**Output**
```

ERROR: file:///content does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found.
```

However, if the following code is executed, then the installation is successful.

**Code**
```
!git clone https://github.com/facebookresearch/segment-anything-2.git

import os

os.chdir('segment-anything-2')

print(os.getcwd())

!pip install -e .
```

**Output**
