Fix queries for block in rust and ecma script (#796)

The blocks in rust and javascript seem very unintuitive to me. When I
select @block.inner in rust for example, this gets matched:
<img width="734" height="153" alt="grafik"
src="https://github.com/user-attachments/assets/f33eb2f8-a4a3-4425-82fe-a8dcc71b578a"
/>
This PR changes this, so @block.inner becomes this:
<img width="734" height="161" alt="grafik"
src="https://github.com/user-attachments/assets/f3ab2989-833e-48ea-96b4-f899451ad1f8"
/>
