* [FEATURE] [API] Add Endpoint for Branch Creation Issue: https://github.com/go-gitea/gitea/issues/11376 This commit introduces an API endpoint for branch creation. The added route is POST /repos/{owner}/{repo}/branches. A JSON with the name of the new branch and the name of the old branch is required as parameters. Signed-off-by: Terence Le Huu Phuong <terence@qwasar.io> * Put all the logic into CreateBranch and removed CreateRepoBranch * - Added the error ErrBranchDoesNotExist in error.go - Made the CreateNewBranch function return an errBranchDoesNotExist error when the OldBranch does not exist - Made the CreateBranch API function checks that the repository is not empty and that branch exists. * - Added a resetFixtures helper function in integration_test.go to fine-tune test env resetting - Added api test for CreateBranch - Used resetFixture instead of the more general prepareTestEnv in the repo_branch_test CreateBranch tests * Moved the resetFixtures call inside the loop for APICreateBranch function * Put the prepareTestEnv back in repo_branch_test * fix import order/sort api branch test Co-authored-by: zeripath <art27@cantab.net>
