Switch verbiage to requesting a PoC for self-host trials.

Proposed changes

• Switch to requesting a PoC for self-host trials. Brings site in line with Revise self-hosted Pulumi documentation content #17941
• Remove tech docs tip/link from onboarding guide. The switching state link no longer exists and the deep dive into self-hosting link infers one can go straight to installing self-host.

Docs Review

PR: Switch verbiage to requesting a PoC for self-host trials

Summary

Clean, straightforward verbiage update across 22 files. The changes consistently replace "sign up for the 30-day trial" with "request a Proof of Concept (PoC)" language, aligning with the updated product page from #17941. The removed info box in the onboarding guide is appropriate since its links were stale.

Issues

No blocking issues found.

Minor observations (non-blocking)

1. Pre-existing inconsistency in capitalization: Some files use "self-hosted Pulumi Cloud" (lowercase) while others use "Self-Hosted Pulumi Cloud" (capitalized) in the same banner text (e.g., components/api.md line 20 vs _index.md line 29). This is not introduced by this PR but could be cleaned up in a follow-up.

2. Link anchor verified: The target anchor #self-hosted-trial exists in content/product/self-hosted.md and the link path /product/self-hosted/#self-hosted-trial is correct.

3. All changes are consistent: The replacement text is identical across all files (with the expected minor variation for the ESC page mentioning "with ESC"). No files were missed or partially updated.

Looks good to merge.
