At the time the dependency on `go.bug.st/relaxed-semver` was added to the project, there was not a release version
available, so it was necessary to use a "pseudo-version" instead.

Since that time, the first release of `go.bug.st/relaxed-semver`, offering the opportunity for more effective management
of the dependency:

- Greater stability through the use of release versions
- Automated update offers from Dependabot

The relevant changes made to `go.bug.st/relaxed-semver` in the interim have been the expansion of the version
constraints syntax, so it will be important for Arduino Lint to use the same version as
`arduino/libraries-repository-engine` and Arduino CLI in order to correctly lint the constraints syntax used in the
library.properties `depends` field.

This will allow the code to be shared by additional rule functions which need this data.

… field elements

Empty version constraints are supported by the Arduino library system (they match any version).

Previously, the regular expression used to split the library name from the version constraint caused these empty
constraints to incorrectly be considered invalid.

Arduino CLI and the Library Manager system have support for specifying version constraints in the library.properties
`depends` field.

This was previously validated as part of the general `depends` field data format check in LP047.

The constraint system has recently been made much more capable through the addition of support for more syntax.

The previous approach for validating the version constraint was a complex and lengthy regular expression in the
library.properties JSON schema. Extending this to comprehensively validate the full range of constraint forms possible
with the new syntax will not be feasible or maintainable.

The new approach is to validate it using the same `go.bug.st/relaxed-semver` module used by Arduino CLI and
`arduino/libraries-repository-engine` to handle the version constraints in this field.

…ibrary.properties schema

A regular expression is employed in the library.properties JSON schemas to validate the format of the contents of the
depends field. Previously, this regular expression was configured to validate the syntax of the optional version
constraint.

The constraint system has recently been made much more capable through the addition of support for more syntax. The
regular expression did not have support for that syntax, which caused valid data to fail validation.

Expanding the already complex and lengthy regular expression to comprehensively validate the full range of constraint
forms possible
with the new syntax would not be feasible or maintainable.

The new approach is to validate it directly via Go code using the same `go.bug.st/relaxed-semver` module used by
Arduino CLI and `arduino/libraries-repository-engine` to handle the version constraints in this field. The schema will
continue to provide a general validation on the `depends` field format.
