Issue on pip when installing Howdy on Ubuntu 24.04

Hello everyone,

I'm facing some issue when installing Howdy on my newly installed Ubuntu 24.04 machine.
The issue seems to be related to pip, but I'm unable to comprehend the point. I've been uninstalling pip many times to see the same result every time.
Can you help ?

```
$ sudo apt install howdy

After detection, Howdy knows how certain it is that the match is correct.
How certain Howdy needs to be before authenticating you can be customized.

F: Fast.
Allows more fuzzy matches, but speeds up the scanning process greatly.

B: Balanced.
Still relatively quick detection, but might not log you in when further away.

S: Secure.
The safest option, but will take much longer to authenticate you.

You can always change this setting in the config.

Start with /var/lib/dpkg/info/howdy.postinst, especially the pip upgrade around line 145, and reproduce the Ubuntu 24.04 installation shown in the report. Investigate why the Debian-installed pip lacks a RECORD file for the attempted upgrade. Done means `sudo apt install howdy` completes configuration without the post-installation error.
