chore: bump default team-operator chart version to v1.25.0

[stevenolen]

Summary

Bump the default team-operator chart version from v1.23.1 to v1.25.0. Workloads that don't pin team_operator_chart_version will pick up these changes on their next ptd ensure clusters run.

Included team-operator changes

Five releases land in this bump:

Version	PR	Change
v1.25.0	posit-dev/team-operator#137	feat: add livenessProbe to Package Manager
v1.24.1	posit-dev/team-operator#136	fix: increase readiness probe timeout and period for all products
v1.24.0	posit-dev/team-operator#131	feat: make Workbench readiness probe path configurable
v1.23.3	posit-dev/team-operator#127	fix: bump controller-manager memory limit 128Mi -> 192Mi
v1.23.2	posit-dev/team-operator#129	fix: add /mnt/load-balancer to XDG_CONFIG_DIRS so Workbench reads load-balancer config

Mostly probe/reliability tuning plus a Workbench config fix and an operator memory bump. No schema changes.

Validation

Deployed v1.25.0 to a staging workload via an explicit team_operator_chart_version pin before this bump:

• team-operator pod came up on v1.25.0 cleanly
• Package Manager rolled, new pod reached Ready with 0 restarts -> new livenessProbe is healthy (not killing the container)
• ReadinessProbe also picked up the timeout/period bump from docs: adding pre-commit functionality #136

Test plan

• go build ./... passes
• CI green
