Get started - Python: Small error in code

## About the bug

**Steps to reproduce:**
List the minimal actions needed to reproduce the behavior.

1. Use the latest docker image (2.7.1). This is the command i ran:
$ docker run -p 8086:8086 -v myInfluxVolume: influxdb:latest
2. At http://localhost:8086/, do the initial setup
4. In the Get Started tab, click on Python
5. Do the steps until "Write data"

**Expected behavior:**

The Python code listing is using "write_apt = client.[...]", which should work (the correct code should be "write_client", not "client")

**Actual behavior:**

Error messsage saying that "client" does not exist.

**Visual Proof:**

```
Traceback (most recent call last):
File "/home/daniel/Lokalt/dbtest/skript.py", line 12, in
write_api = client.write_api(write_options=SYNCHRONOUS)
NameError: name 'client' is not defined
```

## About your environment

**Environment info:**

Linux 5.19.0-46-generic x86_64
Influxdb 2.7.1

**Config:**

Start in the Get Started tab's Python flow and locate the code listing for the "Write data" step. Compare the displayed client variable with the reported traceback; done means the listing uses the correct write_client reference and the Python example no longer raises the shown NameError.
