TLS version negotiation issue

## Bug Report

TLS does not work when targets accepts only TLSv1.2 and tls.min_version set to TLSv1.2

**To Reproduce**
Output accepts only TLSv1.2, not newer. Otel output in fluentbit set to tls.min_version: TLSv1.2
```
outputs:
- name: opentelemetry
match: "*"
host: host
port: port
tls: on
tls.min_version: "TLSv1.2"
tls.verify: on
tls.ca_file: file
tls.crt_file: file
tls.key_file: file
```

Result:

**Expected behavior**
TLSv1.2 should be negotiated and requests should reach the target
