Browser: second fix for linked socket path

[droidmonkey]

• Fix Browser connection is broken #8702

Testing strategy

Tested on Ubuntu with 2.70 upgraded to this commit

Type of change

• ✅ Bug fix (non-breaking change that fixes an issue)

[droidmonkey]

The only downside is that downgrading to anything less than 2.7.4 will break browser integration again. Maybe it is a good idea to remove this link when KeePassXC closes. @varjolintu thoughts? I am not overly concerned, but maybe adding to the troubleshooting guide for linux to manually delete the socket locations as a troubleshooting step.

@droidmonkey At least we've made sure the newer versions will work. I'll add a section about deleting the socket to the troubleshooting guide.
