[Shared] Refresh shared module params logic (#852)

## Summary The "adding_params.md" doc has (or will have) changed substantially (see #839) since the shared module's param logic was last updated. This PR aligns the shared module's param logic with the snippets in the updated docs. Specifically, this refresh includes: - Moving validation logic from `msgServer#UpdateParam()` to `MsgUpdateParam#ValidateBasic()`. - Replacing magic strings of param names with their standard variable counterparts (i.e. `sharedtypes.Param...`). - Improving some local variable names. - Replacing usages of `interface{}` with `any`. ## Dependencies - #809 - #843 - #844 - #845 - #847 - #848 - #849 - #850 - #857 ## Dependents - #851 - #861 ## Issue - #612 ## Type of change Select one or more from the following: - [ ] New feature, functionality or library - [ ] Consensus breaking; add the `consensus-breaking` label if so. See #791 for details - [ ] Bug fix - [x] Code health or cleanup - [ ] Documentation - [ ] Other (specify) ## Testing - [ ] **Documentation**: `make docusaurus_start`; only needed if you make doc changes - [ ] **Unit Tests**: `make go_develop_and_test` - [ ] **LocalNet E2E Tests**: `make test_e2e` - [ ] **DevNet E2E Tests**: Add the `devnet-test-e2e` label to the PR. ## Sanity Checklist - [x] I have tested my changes using the available tooling - [ ] I have commented my code - [x] I have performed a self-review of my own code; both comments & source code - [ ] I create and reference any new tickets, if applicable - [ ] I have left TODOs throughout the codebase, if applicable --------- Co-authored-by: Redouane Lakrache <[email protected]> Co-authored-by: Daniel Olshansky <[email protected]> Co-authored-by: red-0ne <[email protected]>
