chore: remove repo-level PR template

[jamesnrokt]

Why

This repo carries its own .github/PULL_REQUEST_TEMPLATE.md, which GitHub prefers over the org-wide default template published in mParticle/.github. That means new PRs here silently skip the shared template every other @mParticle/sdk-team-owned repo is meant to use. Once this lands, opening a new PR here shows the same org-wide template contributors see everywhere else.

Programme

Standalone change, no programme.

What changes

Deletes .github/PULL_REQUEST_TEMPLATE.md. Nothing else changes. New PRs opened against this repo now fall back to the org-wide default at mParticle/.github (.github/PULL_REQUEST_TEMPLATE.MD).

Linked work

None.

Rollout

Nothing changes in production; if this is wrong, revert the pull request.

Risks

• Nothing can break beyond the text itself.

Risk class: low.

Who

Written by: automated coding agent (Claude Code), on behalf of the requesting engineer — standalone repo-hygiene request, no linked ticket.
Code reviewed before opening: an independent review agent, before the commit was made.
Design reviewed before opening: no one.
Decision this implements: a repo-hygiene request from the repo owner to drop this repo's PR template override so it falls back to the org-wide default. No ticket, no linked record.
Checked: confirmed no file under .github/workflows/ references PULL_REQUEST_TEMPLATE; confirmed mParticle/.github publishes an org-wide default template.
Not checked: nothing else touched, nothing else to check.

Size

Hand-written: 0 lines added, 13 lines removed, 1 file deleted.
Generated: none.

PR Summary

Low Risk
Non-code change that only affects the default GitHub pull request template text.

Overview
Deletes the repository-specific pull request template (.github/PULL_REQUEST_TEMPLATE.md). Future pull requests in this repository will fall back to the organization-wide default template.
