GetTxsEvent returns error if event type contains underscore.

Summary of Bug

In our project, we use IRIS for atomic swaps support between Cosmos ecosystem and other chains. Recently, I have noticed that our tests started to fail after Iris testnet update to 1.4.0-rc1. Which in its turn bumped cosmos-sdk from 0.46.1 to 0.46.4. Iris HTLC module emits event types containing _ character: create_htlc, claim_htlc. Which is not allowed anymore after this #12474 PR was merged. The regex https://github.com/cosmos/cosmos-sdk/pull/12474/files#diff-53f84248611b4e705fd4106d3f6f46eed9258656b0b3db22bd56fdde5628cebdR47 should contain _ to make it work again.

Version

0.46.4+

Steps to Reproduce

Try using claim_htlc.id='2B925FC83A106CC81590B3DB108AC2AE496FFA912F368FE5E29BC1ED2B754F2C' events string with http://34.80.202.172:26657 IRIS node.

Expected result: it should return the transaction emitted the requested event.

Actual result: rpc error: code = InvalidArgument desc = invalid event; event claim_htlc.id='2B925FC83A106CC81590B3DB108AC2AE496FFA912F368FE5E29BC1ED2B754F2C' should be of the format: {eventType}.{eventAttribute}={value}: invalid request"
