docs: fix 'allows to separate' grammar in v2 architecture (_dev)

## Description

In \`content/docs/v2/_dev/architecture/_index.md\`:

> the **collector**/**query** configuration allows to separate the read and write traffic

Suggested fix: "allows you to separate".

Happy to open a PR against \`_dev\` (source for versioned docs).

Open content/docs/v2/_dev/architecture/_index.md and find the collector/query configuration sentence. Update the grammar to use “allows you to separate,” then confirm the wording is correct in the _dev source for the versioned documentation.
