Fixes https://issues.redhat.com/browse/QDOCS-978

The downstream docs engine is unable to render `tooltip`-s, so we need to unwrap the tooltips in the configuration reference into regular text within the table

Example for the `quarkus.datasource."datasource-name".jdbc.transactions` config property:

Before this PR:
```
tooltip:enabled[Integrate the JDBC Datasource with the JTA TransactionManager of Quarkus. This is the default.], tooltip:xa[Similarly to `enabled`, also enables integration with the JTA TransactionManager of Quarkus, but enabling XA transactions as well. Requires a JDBC driver implementing `javax.sql.XADataSource`], tooltip:disabled[Disables the Agroal integration with the Narayana TransactionManager. This is typically a bad idea, and is only useful in special cases\: make sure to not use this without having a deep understanding of the implications.]
```

After this PR:
```
enabled: Integrate the JDBC Datasource with the JTA TransactionManager of Quarkus. This is the default.

xa: Similarly to `enabled`, also enables integration with the JTA TransactionManager of Quarkus, but enabling XA transactions as well. Requires a JDBC driver implementing `javax.sql.XADataSource`

disabled: Disables the Agroal integration with the Narayana TransactionManager. This is typically a bad idea, and is only useful in special cases: make sure to not use this without having a deep understanding of the implications.
```
