Point to the most recent version of duckdb submodule

[hmeriann]

This PR pushes a new submodule pointer in the sqlsmith_smith repository as described here

@Tmonster please take a look. I tried to compile and to run tests - everything worked.

Looks good to me, would like to know first is @samansmink has any concerns (I've never done this before and would like to not break CI or the extension ecosystem)

[samansmink]

I think its fine, basically and extension can either track latest stable, or like sqlsmith is doing now, main. tracking main is a little more confusing because ci might choose a different version than is in the submodule because they are not tied to eachother in any way. The submodule version is currently only used for development.

Note that some extensions do actually use the submodule version in CI, for example: https://github.com/duckdb/duckdb_iceberg/blob/main/.github/workflows/Rest.yml.

@hmeriann can you check that the extension ci tools are also set to the latest duckdb version? v1.0.0?
Then I think this is good to merge.

@samansmink all other references to a duckdb stable version should reference v1.0.0 so I think this will be fine

[hmeriann]

@Tmonster sure, I'll check it
