[text-auditor] Batch fix misleading Bitbucket credential labels and benchmark/help text

## Text Improvements

The following user-facing text issues were found in the repository. Each is a low-effort fix.

### 1. Bitbucket credential descriptions incorrectly refer to JIRA

**File:** `packages/atlassian_bitbucket/data_stream/audit/manifest.yml` (line 72)
**Current text:** `JIRA Username. Needs to be used with a Password. Do not fill if you are using a personal access token.`
**Suggested fix:** `Bitbucket Username. Needs to be used with a Password. Do not fill if you are using a personal access token.`
**Why:** This is the Bitbucket integration and the field title is `Bitbucket Username`; `JIRA Username` is misleading.

**File:** `packages/atlassian_bitbucket/data_stream/audit/manifest.yml` (line 79)
**Current text:** `JIRA Password. Needs to be used with a Username. Do not fill if you are using a personal access token.`
**Suggested fix:** `Bitbucket Password. Needs to be used with a Username. Do not fill if you are using a personal access token.`
**Why:** Same terminology mismatch as above.

### 2. CLI message in testsreporter is awkward/ungrammatical

**File:** `dev/testsreporter/testsreporter.go` (line 61)
**Current text:** `Skip creating GitHub issues, hit the maximum number (%d) of tests to be reported. Total failing tests: %d.`
**Suggested fix:** `Skipping GitHub issue creation: reached the maximum number (%d) of tests to report. Total failing tests: %d.`
**Why:** The current sentence structure is awkward and unclear in user-facing output.

### 3. `Rally benchmarks` doc link points to pipeline benchmark page

**File:** `docs/extend/elastic-package.md` (line 61)
**Current text:** `- [Rally benchmarks](https://github.com/elastic/elastic-package/blob/main/docs/howto/pipeline_benchmarking.md)`
**Suggested fix:** `- [Rally benchmarks](https://github.com/elastic/elastic-package/blob/main/docs/howto/rally_benchmarking.md)`
**Why:** Link label and target topic do not match; users clicking Rally docs are sent to pipeline benchmarking docs.

## Suggested Actions

- [ ] Replace the two `JIRA` credential descriptions in the Bitbucket audit manifest with `Bitbucket` wording.
- [x] Rewrite the testsreporter max-threshold message to a grammatically clear sentence.
- [ ] Update the Rally benchmark link target in `docs/extend/elastic-package.md` to the Rally benchmarking page.
