Electron Releases

Description of Change

• Since #47534, fork PRs have been failing trying to use siso with the error: PermissionDenied desc = Failed to authorize to Execute() against instance name "projects/electron-rbe/instances/default_instance": Permission denied (eg see https://github.com/electron/electron/actions/runs/17621870487/job/50277249344#step:24:33167).

Since fork PRs only have read access to the RBE cache that siso uses, this PR fixes that error by setting the RBE exec strategy to local which has the following operation:

Use Local Execution, Remote Caching (LERC). Checks the remote cache for action matches and uses existing results if a match is found. If not, execution of the action is performed locally.

Successful builds with this strategy can be seen here: https://github.com/electron/electron/actions/runs/17739060216?pr=48320.
