chore(backend): upgrade sqlx to ^0.7

[mrl5]

related to #1858

known sqlx 0.7 breaking changes:

• SQLx Next (0.7+) Tracking Issue launchbadge/sqlx#1163 (comment)
• PgHasArrayType is not implemented for Vec<i64> launchbadge/sqlx#2611
• the trait bound &mut Transaction<'_, Sqlite>: Executor<'_> is not satisfied launchbadge/sqlx#2606
  • https://github.com/launchbadge/sqlx/blob/afb6b1066e61f8e3875f530d96cfb5a299f13fda/examples/postgres/transaction/src/main.rs#L14-L17

    In 0.7, Transaction can no longer implement Executor directly, so it must be dereferenced to the internal connection type

blocked by:

• PgHasArrayType is not implemented for Vec<i64> launchbadge/sqlx#2611
  • fix(postgres): PgHasArrayType is not implemented for Vec<i64> launchbadge/sqlx#2617

upstream fix available in 0.7.1 via launchbadge/sqlx#2619

⚠️
@rubenfiszel using sqlx-cli version (in terminal) that's in sync with sqlx version (in windmills Cargo.lock) is probably the most important take away for this PR.

On the other hand I think above is only relevant for contributors that need to run this

windmill/backend/README.md

Lines 18 to 22 in aaaf85a

	### Compile sqlx for offline ci
	```
	cargo sqlx prepare --merged -- --bin windmill --features enterprise
