ci: Fix FIH YAML result parsing
The running test was generating an YAML output with the following line:
```
last_line: ' Description: 'ECDSA signature test of attest token''
```
This string comes from the test with the single quotes, and using single
quotes twice break the YAML format, so this commit changes the string
after last_line to be enclosed in the double quotes.
