Ireland suspended its participation in the European Agreement on the Abolition of Visas for Refugees on 19 July 2022, for a period of 12 months. This means that 1951 convention travel document holders need a visa to travel to Ireland. Beyond this date, it is possible that Ireland will announce a further suspension at some point. Convention document holders should assume they will need a visa to travel to Ireland beyond this date.
The Irish government provides a tool for determining what visa you require to travel to Ireland. Putting in your details shows that you do not need a visa to travel to Ireland for any stay up to 90 days.
Ireland is a party to the European Agreement on the Abolition of Visas for Refugees. Since you have a 1951 Convention document issued by another party to the agreement, you can travel without a visa. However, note that the UK is not (anymore) a party to the agreement. You would need a visa if you were to travel to Ireland via the UK, and you would need a visa if you were to cross the border into Northern Ireland, despite the lack of border controls.
