fix: Bump executor crate version (#1865)

The previous release of v0.25.3 had a failing test because of a mismatch
in crate version. This PR bumps the executor `CRATE_VERSION` to match
the correct crate version.

 ### Fixed
 
+- [#1865](https://github.com/FuelLabs/fuel-core/pull/1865): Bump executor version to 0.25.3. 
 - [#1862](https://github.com/FuelLabs/fuel-core/pull/1862): Replaced instances of `Union` with `Enum` for GraphQL definitions of `ConsensusParametersVersion` and related types. This is needed because `Union` does not support multiple `Version`s inside discriminants or empty variants.
