[javascript] [typescript] [php] [ruby] Simplify url parameter replacement code

[coffeemakr]

Generate url parameter tokens without string concatenation or string templates.

I used 2 regexes:

`\{\$\{"\{\{([a-zA-Z]+)\}\}"\}\}`
'\{' [+.] '\{\{([a-zA-Z]+)\}\}' [+.] '\}'

With the replacement

{{=<< >>=}}'{<<$1>>}'<<={{ }}=>>

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in WSL)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR solves a reported issue, reference it using GitHub's linking syntax (e.g., having "fixes #123" present in the PR description)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Summary by cubic

Simplified URL path parameter replacement in generated clients by using literal tokens like '{param}' instead of concatenation or template strings. This makes the code smaller and easier to read with no behavior changes.

• Refactors
  • Generate path replacements using literal '{param}' tokens via Mustache delimiter swaps, replacing patterns like '{' + '{{baseName}}' + '}' and `{${"{{baseName}}"}}`.
  • Applied across JS/TS (typescript-axios, typescript-fetch, typescript-jquery, typescript-node, typescript-redux-query, Javascript-Closure-Angular, Javascript-Flowtyped), PHP (php, php-nextgen, psr-18), and Ruby templates.
  • Regenerated samples to reflect the new token style.

^{Written for commit 30b0a16. Summary will update on new commits.}
