Can't show ansi color on windows if use git bash

## Description

When using `fire` in Git Bash on Windows, the `initialize_or_disable` function in the `formatting_windows.py` unnecessarily invokes `colorama.init(wrap=True)` even though Git Bash already supports native ANSI escape sequences. This behavior causes issues, such as double-wrapped output or incorrect handling of ANSI sequences, which can lead to degraded user experience or unexpected output.

## Steps to Reproduce

1. Use Git Bash on a Windows system.

1. Run a script that uses `fire` with formatting enabled.

1. Observe that the output is handled incorrectly due to the invocation of `colorama.init(wrap=True)`.

## Root Cause Analysis

The initialize_or_disable function currently does not differentiate between Git Bash and other Windows environments like `cmd.exe` or `powershell.exe`. Specifically:

- Git Bash natively supports ANSI escape sequences.

- The function does not explicitly check for Git Bash and thus assumes it must handle formatting via `colorama`.

- This leads to `colorama.init(wrap=True)` being invoked unnecessarily, causing redundant processing and potential output issues.

## Proposed Solution

Add an explicit check for Git Bash environments in the `initialize_or_disable` function. This can be achieved by inspecting environment variables such as `MSYSTEM` or `TERM`, which are typically set in Git Bash.

Additionally, provide a configuration option to control whether the formatting_windows functionality is enabled or disabled. This will allow users to explicitly manage how formatting is handled.

## Suggested Changes
Modify `initialize_or_disable` to detect Git Bash:
```python
def initialize_or_disable():
is_git_bash = os.environ.get('MSYSTEM') or os.environ.get('TERM') in ['xterm', 'xterm-256color']
if is_git_bash:
print("Detected Git Bash, skipping colorama.init")
return # Skip colorama initialization for Git Bash

# Existing logic for colorama and ANSI initialization

```
Add a configuration flag to enable or disable the `formatting_windows` logic explicitly. For example:
```python

ENABLE_FORMATTING_WINDOWS = os.environ.get('ENABLE_FORMATTING_WINDOWS', '1') == '1'

if ENABLE_FORMATTING_WINDOWS:
initialize_or_disable()
else:
print("Formatting for Windows is disabled")
```
