Both typos are real and both are still on development as of today, so this is worth taking. Verified:

• docs/datasources/couchbase/page.md:41 — "serup"
• pkg/gofr/grpc_test.go:302 — "unadressable"

Those are the only two occurrences in the repo, so the sweep is complete, and unaddressable matches the spelling already used at grpc_test.go:290. CI is green and the branch is clean against development.

One change before I merge it.

docs/datasources/couchbase/page.md:41 — the verb form is two words

"setup" is the noun; the verb is "set up". Correcting the typo to "setup" leaves the sentence ungrammatical, and it would be the only to setup in docs/ — the three existing instances are all to set up (websocket/page.md:18, load-testing/page.md:122, connecting-redis/page.md:17).

Don't forget to set up the Couchbase cluster in Couchbase Web Console first.

Title

Could you reword it to Conventional Commits? The title is what lands in history on squash. Something like:

fix: correct "serup" and "unadressable" typos

One note, not a request

Worth knowing why this reached development at all: our typos check runs across the whole repo, but crate-ci/typos v1.50 doesn't carry either word — it knows adressable -> addressable but not the un-prefixed form, and serup isn't in its dictionary. That's why the check is green on development today with both typos still present. If we want the linter to hold this line in future, a custom correction in typos.toml does it:

[default.extend-words]
unadressable = "unaddressable"

Separate concern from this PR though — please don't widen the diff for it.

Everything else is approvable. Fix the set up line and the title and I'll merge.
