chore: Drop support for deprecated TLS versions (#2945)

Browse source 
* chore: Set `TLS_INTERMEDIATE_SUITE` to only use TLS 1.2 ciphersuites

Removes support of the following cipher suites that are only valid for TLS 1.0 + 1.1:

- `ECDHE-ECDSA-AES128-SHA`
- `ECDHE-RSA-AES128-SHA`
- `ECDHE-ECDSA-AES256-SHA`
- `ECDHE-RSA-AES256-SHA`
- `DHE-RSA-AES128-SHA`
- `DHE-RSA-AES256-SHA`

* chore: Update TLS version min and ignore settings

These are now the same as modern settings.

* fix: Remove min TLS support workaround

No longer required now that outdated TLS versions have been dropped.

* tests: Remove support for TLS 1.0 and 1.1 ciphersuites

* tests: Remove support for TLS 1.0 and 1.1 ciphersuites (Port 25)

The removed SHA1 cipher suites are still supported in TLS 1.2, thus they've been excluded for port 25 via the `SHA1` exclusion pattern in `main.cf`.
