Issue:
[otelmongo] bump semconv to 1.26.0
### Problem Statement

otelmongo is currently using [semconv/v1.17.0](https://github.com/open-telemetry/opentelemetry-go/pull/3599), suggest updating to [semconv/v1.26.0](https://github.com/open-telemetry/opentelemetry-go/pull/5476).

### Proposed Solution
key/value pair changes migrating from 1.17.0 to 1.26.0 include:

   </td>
  </tr>
  <tr>

   <td><code>DBQueryText</code>
   </td>
   <td><code>db.statement</code>
   </td>
   <td><code>db.query.text</code>
   </td>
   <td>There is no deprecated analogue to `db.statement` according to the documentation. <code>Db.query.text</code> seemed like a natural fit.
   </td>
  </tr>
</table>


#### Alternatives

Since these fields are deprecated, there is no alternative other than leaving the semconv version static.

#### Prior Art

NA

### Additional Context

It's worth noting that this is a breaking change if telemetry key/values are considered stable. 

Pull request description:
otelmongo: support OTEL_SEMCONV_STABILITY_OPT_IN for v1.26.0 semconv
Resolves #6171, #2165

The specifications for maintaining multiple semantic convention versions is documented here: https://github.com/open-telemetry/semantic-conventions/blob/main/docs/database/database-spans.md. 

To use a non-default version:
```
export OTEL_SEMCONV_STABILITY_OPT_IN=database
```

To include both v1.26.0 and v1.21.0:
```
export OTEL_SEMCONV_STABILITY_OPT_IN=database/dup
```

To include the default (v1.21.0) version:
```
unset OTEL_SEMCONV_STABILITY_OPT_IN
```
