There's no known breaking changes in this release. However, we did rewrite the Stored Procedure engine. As far as we know they changes only improve correctness but it's a big change so we made a minor version bump.

• 9171: dolt status user contribution
• 9167: test for temporary tables in stored procedures
  The stored procedures rewrite fixed an issue where temporary tables aren't able to be created and selected within a stored procedure; this PR adds tests to specifically test for that case.
  fixes: #8762
• 9165: go: keymutex: Improve cleanup and refcnt implementation so that we can keep the mutexes map clean in more cases.
• 9155: fix status command after removing origin from remote
  Fix #9130 and #9069.

• 9120: Consistently use pointer receiver for ByteArray
  Similar to #9100
  For structs that are exclusively used in interfaces, there's no reason to not use pointer receivers instead of value receivers. Using value receivers can cause the struct to be copied every time the method is invoked.
  Pointer receivers are also more correct here: copying the struct means that changes to the ImmutableValue field (such as setting its Buf field in ImmutableValue.GetBytes) won't be saved when the method exits, defeating the caching of values loaded from storage.

• 2964: Unwrap inputs to REGEXP_LIKE, REPLACE, and RPAD/LPAD functions.
  These are a couple more functions whose inputs aren't being unwrapped. If the inputs come from a column with a TEXT type, then they won't be converted to strings and the functions will fail. This PR fixes this by making sure that the inputs are converted.
  We missed this previously because although we have tests for these functions, none of them tested getting the inputs from TEXT columns of a table.
• 2963: From unixtime
  Merged main from dolthub/go-mysql-server#2910
• 2962: fix infinite recursion with recursive stored procedures
  fixes: #8763
• 2961: fix prepare statements and user vars in stored procedures
  This PR adds tests for user variables within Stored Procedures.
  Additionally, this PR has changes so that we don't double parse PREPARE ... FROM ... statements, which also allows them to be used in the updated Stored Procedures call.
  fixes: #8911
• 2959: Doltgres literal support
  This makes literal expression implement the sqlparser.Injectable interface so they can be used in Doltgres AST conversion.
  Also exports fields so literals can be edited in place (required for how Doltgres processes these in a couple places).
  This is an alternative to dolthub/go-mysql-server#2946.
• 2955: Add support for UPDATE ... RETURNING
  Related to: dolthub/doltgresql#1421
• 2851: rewriting stored procedures
  This PR reimplements Stored Procedures so that queries are run individually, while maintaining context through the use of a stack.
  companion pr: dolthub/vitess#402
