fix: remove skip ci from workflow (#468)

### Description

<!--
Summary of change.
Example: Add sepolia chain
-->

When both combine or optimize-svg have changes, whoever finishes last
would not be able to push because the other one already commited
changes. I removed [skip ci] because it is not necessary and the initial
thought was that it would loop but that should not be the case. Once one
of the workflow updates it will trigger another check and if the other
workflow has changes it will check again and do the proper changes.

### Backward compatibility

compatible.

Yes/No

Yes

### Testing

<!--
Have any new metadata configs and deployment addresses been used with
any Hyperlane tooling, such as the CLI?
